    Come on Ray, why didn’t you just open the windows and let some of that Al Gore Global Warmair in?

    Jeff – If I had known Al was in the neighborhood, I just might have!

    Barrie – The funny thing is (there’s always an irony, right?) that right after I fixed it, the outside temperature jumped up into the seventies. It even broke eighty today! Oh well, at least it is fixed for next year.

    I also let oil run out, twice in fact. Having a professional prime the burner is costly. My burner is out now but the tank is 5/8 full.
    I had called a company called US Chimney to clean the flue this morning. Instead of a clean chimney I got a $2400 estimate for a supposedly much needed liner. Once they left the burner had stopped working and the reset button was in the lock out mode.

    Encouraged by the instructions you have outlined I was going to attempt to prime the pump myself but I figured I’d try the easy fix first. I put to use what learned; I pressed the reset button for 40 seconds – Motor turned on the 4th try.

    Many, many thanks to you.

    I just put $900 of oil in my tank after I unknowingly let it run out….hey at that price I’m sure it wont be the last time. My heater wouldn’t ignite…no more money left to call a repair man!!!!I read your blog, and followed your directions to prime the boiler. WOW! I did it!
    I want to thank you..God Bless You for sharing your knowledge without expecting anything back. That is rare. Thank -You

    You saved me and my marriage ! ( a good thing i think) Ran out of fuel, bled air , then label says ” light flashing .5 seconds = press reset for lockout /// light flashing 2 seconds (my case ) recycle.” What the heck was recycle …only one reset button called oil company and was told there might be another very tiny reset button on the motor itself …never found one. Had instictively held rest button longer but never the 40 seconds.
    thank you.

    I just got my furnace going …left a comment … only then noticed the web site that helped me was not a furnace company from my google search but from a Christian minister’s support site. Are you related to a Tom Fowler who lived close to Huntington Beach ca. in the early 80’s ? He was a retired engineer who did handyman work often for free to needy people.

  14. Ray Fowler
    October 19, 2008

    bob – Hey, I’m always glad to save a marriage! I’m glad you found the article helpful. I don’t know why they don’t print the 40-second recycle instructions right on the lockout switch. I am sure it would save a lot of people a lot of trouble.

    And yes, this probably is a strange article to find on a pastor’s website, but I try to post all sorts of things of interest as I come across them. I don’t know Tom Fowler, but I used to live in Burbank, California from 1984-1988.

    Thanks for stopping by! – Ray

    Thank you so much for posting this information in an easy to read manner, with some additional useful tips.

    It worked perfectly for me. My wife will be enjoying a warm shower again very soon. :)

    One key thing to note in the order of steps that I missed the first time is to leave the bleeder valve open when pressing the reset button, and then once you have a good stream, you may need to hit reset one more time after closing the bleeder valve if it cuts out before you can get it closed.

  16. Ray Fowler
    October 21, 2008

    Mike – Thanks for the clarification on leaving the bleeder valve open when pressing the reset button. Very important.

    Here it was, New Year’s Eve as I sat beside my wife in front of the TV watching the Canada/U.S. Junior Hockey game saying – “It must be getting very cold outside, I can feel it in the house”. I got up to check the thermostat and it was a few degrees lower than I normally set it and I couldn’t hear the furnace. Oh oh!

    Four or five years ago, we were forced by the insurance company to replace the oil tank, which was probably 50-plus years old. There were no problems but that is their way to make sure there are even fewer oil spill problems, especially with a 200 gallon tank that was in the basement. So we changed it but we decided to install the tank outdoors just in case the insurance company decided 5 years down the road to force us to move the tank outside.

    We are in Northern Ontario, Canada and it sometimes gets quite cold and this creates other problems for an outdoor tank – like water in the bottom of the oil tank.

    This same problem happened a couple of years ago and it turned out that the line was frozen and oil was not getting to the burner. My wife watched the mechanic pour boiling water on the outside line from the bottom of the tank to thaw it out. Eventually the repairman got it going but we weren’t sure what he did after thawing the line.

    So during last night’s game I was boiling water and pouring it as best I could on the exposed oil line outside. After a few pours I cracked open the line in the basement between the filter and the pump and I was getting oil but no ignition. I set up some electric heaters around the house and went to bed after seeing watching count the ball down.

    As soon as I awoke, which was around 4 am I went online to look for a solution because the last time this happened it cost around $100. Today is a holiday so I expected that it might be $200 or more this time around.

    I found this site along with Wikihow and eHow with this solution and I decided to be brave and take a shot at it. I didn’t have a rubber hose but I had an old piece of extension cord that I cut into about a 15″ piece. I then pulled out the insides and cleaned it out, then tried it on the bleeder screw. The old rubber was very stiff and it almost fit but in order to get it to fit better I heated the end of the hose in boiling water and then slipped it over the nipple. I had already loosened and then snugged the bleed screw back up by hand. I had an empty paint pail and I was ready for action.

    I looked inside the combustion chamber previously to make sure there was no oil laying in there, I made sure the thermostat was set higher than the room temperature and I made sure I knew how to shut the burner motor off in case anything went wrong. I was alone doing thise so there couldn’t be any mistakes.

    Now the moment of truth … I hit the reset button while I opened the bleed screw. Air and oil came out of the hose into the paint can, coughing and sputtering a bit at first and then it began to flow smoothly and evenly. Once the flow was good, I carefully closed the bleed screw and once it was closed the burner lit and I was back in business!!

    I know this is a long-winded response but I had to share my satisfaction at saving probably $200 on this repair bill. And I would especially like to thank Ray Fowler and people like him, who have taken the time to put helpful articles like this one on the net for all to benefit from.

    Thank you Ray Fowler and I hope you and your family have a great New Year. And a Happy New Year to all. I hope 2009 ends better than 2008 did for some people!!

    January 1, 2009

    J Mac – It is responses like yours that make it all worthwhile. And I am very impressed at your ingenuity in using an old extension chord for a rubber hose. Now that is truly Do-It-Yourself! All the best to you and yours for the New Year.

    The 40 second hold on the reset button saved me a Service call. It hit -20 here last night and pipe froze, house dropped to 48 before we realized what was going on. Called 2 places for service and went outside with a hairdryer for an hour( 7a.m. 4 degrees)to try to thaw the line. wouldn’t reset. Broke out the propane torch. 2 hours of heating lines and trying to bleed. Still locked out. Really wanted the service guys to show up! Finally, typed frozen lines in the search engine and you popped up. held the button for 40 seconds and presto!!! Thank you sooooooo much for posting this info. Also had the pleasure of turning one of the repair guys away 15 minutes after reading this article.

  21. Ray Fowler
    January 16, 2009

    Dale – Glad it worked for you!

    Jim – Great story. I don’t envy you standing outside with a hairdryer at 7am in 4 degree weather. I’m glad you got the furnace to reset before the service guys showed up.

    Hi Ray,

    With money tight, I kept putting off ordering more oil, and then foolishly ran out the other night. Thankfully I have good friends, who loaned our family some space heaters to get through the night. But, when I couldn’t get the furnace going the next AM after the oil was delivered, I was confused. My husband had already left for work and thought I’d try and find something online before calling a repair man. I stumbled across this article and from your directions I was able to find the bleeder valve and voila! As a woman, it felt downright empowering to be able to get it running again on my own. (Plus, it did assuage some guilt of having gotten in this position in the first place).
    Thanks so much!

  23. Ray Fowler
    January 22, 2009

    Dani – You’re welcome! Isn’t it a great feeling fixing something yourself? And that reminds me. My oil tank is getting low. I better order some before I have to follow my own instructions all over again!

    I just moved to the east coast for the first time, and had never even heard of an oil furnace much less seen one. This morning I received my second oil delivery of the year, and nothing. No heat. I called the company and they quoted me $150 to come fix it. More from an absolute lack of ability rather than unwillingness to pay, I went on the hunt for information. I found your site. An hour later, lo and behold, the girl who didn’t know oil heat from a hole in the ground now has a toasty warm apartment! THANK YOU so much for this great information!

    I have an oil furnace and on the burner cover it says Mectron 3 and the name Riello. I let it run or of oil by mistake as it is only used when I need to bump up the heat in my tool barn/shed. I have oil and lots of “spark” but I can not get it to ignite. If you have any info as to why I would appreciate it. I am burning mostly diesel fuel with a little kerosene mixed in. I have the burner out and I can see what it is doing when it is trying to fire. I am aware of the hazards but it was the only way I could see what the unit was doing. Fire fighters are probably the worst for taking changes. :)

    February 9, 2009

    Harry – I wish I knew. Did you try to prime the pump as in the instructions above? Does anyone else have any ideas?

  30. Harry
    February 9, 2009

    Thanks for the reply. I do have good flow out the end as I have it set up to fire outside the furnace so I can watch it. The oil sprays nicely in a cloud and I can see the spark being “blown” by the spray of the oil. I would have thought that the spark would have ignited the oil spray but it just cuts off after a few seconds of spraying the oil while the ignition is sparking.

  31. Ray Fowler
    February 9, 2009

    I’m stumped. Anybody?

  32. Rob
    February 25, 2009

    Harry, it sounds as tho your oil nozzle may be clogged and not spraying in the correct pattern to ignite. Also for those wondering about the 40 sec reset lockout. This was put there intentionally to keep homeowners from hitting the reset too many times. Hitting the reset multiple times is not a problem if your oil pump isn’t primed, but if it is and you’re spraying oil into the furnace and it isn’t igniting (seperate problem all together) you could create quite a hazardous situation if the furnace did actually ignite after hitting the reset 3-4 times. Great guide for priming an oil pump tho, as a hvac contractor i wish everyone were able to do this themselves! We do not like giving out hefty repair bills no more than anyone likes to pay them.

  33. Ray Fowler
    February 25, 2009

    I woke up on Sunday morning to a freezing house. After investigation, I found out that my oil tank gauge is stuck at 1/2 tank; however my oil was long gone. Went w/out heat until today-Wed.(oil was delivered on Tues.). Thank you for this website because I certainly did not want the expense of calling someone to get the heat back on. I got the 3/8 wrench, tubing, and container and at this very moment the temperature has climbed from 53 degrees to 67 degrees and counting!!!

    Thanks bunches

    Hi. My oil burner stopped working 10 days ago. I assumed, as in the past, that it was time to change the filter, which I did. I also changed the nozzle. Could not get the burner to oil. I have 22″ of oil (as measured with a dip stick) in an underground oil tank where full is approx 46 inches. It has not been that cold out. Approx 30 & 40’s F. I tried to prime and prime and still nothing. I replaced oil pump and coupling (motor to pump) thinking this could be it. The coupling was a tad worn but still very much functional. Still could not get oil. Motor is working great. Tried over and over again to bleed/prime system and does not work. I have a two line system. Been working great for 20 years. I then disconnected oil “in” line and hooked up air pressure line to blow line out in case something was plugged in it. I then hooked up a shop vac to the line to try to get oil and could not get any. I am not sure how much suction is required to get the oil flowing. Perhaps a shop vac would not even do it. I don’t know. When I ran [new] pump with inlet line disconnected, the suction seemed low (based up putting my finger by the port) to me but then again I don’t know what normal suction feels like. Anyhow, everything seems to be working correctly except I get no oil. Any suggestions or help?

    Ed – Don’t leave us hanging, tell us more. Is there a hidden danger in one of the steps above, if so what should we be looking for? I don’t want anyone to do anything foolish, but I don’t want people to be afraid to fix something if they can fix it.

  44. ed
    April 29, 2009

    you should be looking for a trained service person. A person with 2 mill. insurance and a truck with 5 thousand dollars of stock and equipment. On call 24/7 willing to spend min.2 hrs any time of day or night to drive to your cold house to rip you off for 100 bucks.A fter reading about auto workers wages i am looking for a better job lol lol . joking a side oil burners are sneaky they stop for a number of reasons. even tec. in canada dont like working on them they are safe but must be understood. picture this,a person thinks they ran out of oil,but are just very low,adds 10 gal and starts to bleed, burner ignition is not working it wont start ,so they keep trying 10 to 15 times ,oil is sprayed into chamber for say 45 sec. each time. the oil will leak thru to floor of furnace. On the 16 time the transformer will ignight. oil vapour has gone up the chimney and soaked everthing there is more fire than you know what to do with. the best is yet to come, now the fan wants to come on. pic. this the heat exchanger is on fire .the inside of the furnace is on fire .the chimney is on fire.you are now going to get your duct work cleaned with fire get the pic. not to scare peps .but this did happen to me.I just got there on his last try to start the burner the chimney lite up like a roman candle, very nice,igot the fire out in time.no real damage. soot everwere. cust had no insurance. whole house had to be cleaned even tooth brushes note. i felt so bad i did not charge him.so the next time i come to your house at 2am with knowledge,tools,parts,insurance,to rip you off for 100 think about it . this is not intended to scare peps.oil is safe. Gas in our cars fill then every day no problem. why would peps smoke while filling up .We even have notices posted. thanks for letting me rag onbut this started many years ago .the co i worked for would not let the oil drivers start the burner for fear of liability ed

  45. Ray Fowler
    April 29, 2009

    Ed – Thank you for taking the time to give us some more details of what could go wrong. It is some pretty scary stuff.

    I take it you are an oil burner tech, and I hope you didn’t take the comments here as people saying that techs are ripping them off when they charge $100 for a service call. That is a pretty standard fee for any type of call to a home nowadays. However, it is still an expense that people would like to avoid if they can do it themselves.

    Thanks for giving us amateurs some words of caution when we try this stuff by ourselves. And all the best with your business!

    Ray
    Thank you, thank you, thank you! Furnace shut down yesterday, which means no hot water also. Called our service tech, still waiting for a call back and it is now 4:30 Friday afternoon. With 1/2 tank of oil, it would appear I had a clogged filter. Changed out the filter, and then followed your instructions on starting the boiler. Had to bleed the lines twice. But on the second try after the 40 second reset you put in the instructions off she roared. Am I smiling? You bet. Saved myself a 100 dollar service call with a 2 dollar filter and 15 minutes of my time. Not a bad deal. Next I would like to know how to change the nozzle and I think I am all ready to do all my own furnace upkeep, and the heck with Ed the Service Tech on the previous comment. It is nearly summer. I watched my tech do precisely the same things I did, including sitting and waiting for the smoke to die down when the furnace came on. I was assured that would stop by the tech who serviced the furnace in December. It did then and it did now. What I would like to know from Ed what is it he would do so differently?

  47. Ray Fowler
    May 15, 2009

    Sandee – Congrats on getting your furnace up and working again. It sure feels great to do something yourself and save some money in the process.

    I wouldn’t dismiss Ed too quickly. I appreciate him taking the time to share with us the cautions that he did. And I am guessing there will be times when my furnace needs repair beyond priming the pump, and then I will be very glad for the Eds out there who have the training and experience I lack.

    Thanks for commenting and all the best!

    This is a great write-up. The internet has empowered us all with the wealth of knowledge to tackle many tasks we would never attempt to do in the past. This is no exception. However, don’t lose sight of the saying “a little knowledge is a dangerous thing.” Do take the effort to understand the basic principles and dangers of the device you are working on. Oil burners require fuel, air, and ignition for combustion. This write-up addresses the specific condition of fuel starvation as a result of air in the fuel system commonly caused by running the oil tank dry and is not a cure all for every oil burner issue. Unlike water, fire and electricity are far more dangerous. Be careful, be sensible… know your limits. This is not to scare anybody but a reminder of the potential danger. I’m not a professional… just a well rounded DIYer.

After making a service call and waiting for awhile i decided to take action myself. o be honest i didn’t know i was out of oil completely, but after filling the oil tank and getting nothing. I knew there was something wrong but just didnt know what it was. But after reading your post, i started priming on my own. HEAT is on….and i am a happy camper. THANKS RAY

    Lots of good info; I have had to prime an enpty tank before but this time I am afraid it might be something more.
    I opened the bleeder valve and held down the button but all I get is a little air. I have done this fifteen times, Could it be something else?
    My wife and I scrached up enough money to buy 100 gals we
    will not be able to pay a service call

    December 26, 2010

    Ran out of oil because the landlord forgot to call. :/ Had the Oil Co. come and put oil in the tank the morning after Christmas during a snow storm. On the phone they said the oil delivery guy would most likely have to prime the burner in order to get it running.. That was news to him! He didn’t know how to get it running and said a tech would have to come.

    So, instead of calling an emergency tech to come out in a snow storm I found this page. What the heck did I do before the internets?! ;) Well, after a few tries at priming it still didn’t start. However, after the 50 second reset switch method I, my gf, my cats and fish are very warm and happy once again. Thank you!

    A question: When priming I could not get more than a drip of oil every second or two. Shouldn’t I have been able to get a good stream of oil to come out?

    THANK YOU!!!!! I ran out of fuel and could not get them to deliver…..went down to fuel station and got 10 gallons of diesel….did as you instructed…warm house,girlfriend and weekend saved….still thinking of how much I just saved…..Portland is in need of affordable oil tech…

    Ray, thanks from yet another delinquent simian who chose to cross fingers and hope rather than check the tank indicator. We got some oil today after being out for a few days and my wife is even talking to me again! I’m kidding, she’s not but at least it’s warmer! :)

    Our oil ran out, and my mother genrously offered to purchase 150 gallons for us (we have a 9 month old). So, they put that in today and the gentleman showed me the re-set button and told me to try it after the oil had setteld for an our. I have pressed re-set numerous times. Even pressed it for 45 seconds. The unit seems to start up and run for about a minute (or a little less) and then stops. I don’t see a flame at all. I have bled the fuel line…there does not seem to be any air and the oil comes through looking nice and clean. We really want to avoid a service call…we avoided getting the oil ourselves precisely because we cannot afford it!!!!

    Any suggestions?
    Chris

    Chris – I wish I could help you, but it sounds like you have an additional issue beyond what this article addresses. I hope you find your solution without having to pay for a service call.

    Ray,
    So glad I found this web-site. Am a senior citizen and ran out of oil and had it filled Thursday and furnace would not come on after hitting the re-set button several times. I do remember once the oil man had to do it for me and I also knew about bleeding the line but was not quite sure how to do it as I do have limited vision and after reading much here just went down to my basement and held the re-set for the 40 second and then released it and the furnace came on. Your site was very valuable to me and so glad I found it. Thank you so much and God Bless you for the help you give to people.
    Furnace is now running and I just heard the fan come on so we should warm up pretty quickly now. Incidentally oil here in Portland, OR was 3.66 a gallon and I am sure going much higher. And I do have five little rescues here but we were not freezing but were cold and not very comfortable. Thank you so much again for this valuable information.

    I followed the recommendations listed above and it worked like a charm (your gonna love this stuff when your done)I closed the bleeder valve after each cycle of the oil burner and about 7 bleeds in we had a steady flow (a lot of stop and starts with the flow)!

    I know this is an old post, but I wanted to say thank you so much! Unfortunately my bleed line is bigger than the 1/4 inch rubber tube, so we just used beer bottles to catch the oil. Only needed to hit the reset once to get a steady stream, the furnace started as I was tightening the bleed line and now we have hot water!

    Thanks for the help. I forgot it was 40 seconds and not 15. I guess after all this rain { 1 week worth } my underground tank has water in it and now I’m in the process of bleeding all the water out. Perhaps it will take me 2hrs :{

    I too ran out of oil & got diesel to hold us over, but the furnace would not turn on. I pressed the reset button, tried bleeding the valve but nothing happened. I thought my only hope was to call a repairman & spend more money we don’t have. Then I came across your post about holding the reset button down for 40 seconds. It took two tries but then oil started spitting out and the furnace turned on after two tries. I’m so excited & relieved right now!!! Thanks for sharing your story & helping me (and clearly many others!)God bless.

    Thanks for the tips, i’ll leave one in return. Home heating oil, deisel, and kero are all the same thing. Diesel has a dye in it to indicate road taxes have been paid. Kero is cheaper, since ur not paying the road tax.

    Me too, me too. I ran out of oil. money’s tight. used 5 gals of diesel to hold over. No fire! Phone call to my diy buddy who said the nozzle is probably clogged. I took off the motor. Probably not a great idea. Got the nozzle off. Even worse idea. really nasty dirty. I used dish soap and hot water and a needle threader wire from my wife’s sewing box to clean out nozzle. I blew a soap bubble through the nozzle, so I knew it was open. [Don’t try this at home, I am a professional . . . idiot] Reinstalled tried to run it with no luck. I was sunk. Called the oil people. You’ll need a “prime and start”. Cost $150 I wondered if there was a diy blog about priming a furnace. Went upstairs. thought that if it wasn’t rocket science, I’d give it a shot. I went to the internet and found your article. I helped my buddy bleed brakes so I knew something about it. Great instructions every body. But the bleeder looks just like the nit on the brake cylinder. At first I thought it was a grease zert.
    1st bleed: dirty black fuel oil Like italian dressing. second: cloudy red; third: foamy oil from the air pocket that came from the space before new oil; 4th time clean clear fuel and before the motor shut off on its own, when I closed the bleed screw with the tube still connected, the furnace turned on immediately.
    the “blood” from the bleed was so nasty, I decided not to save it.

    I agree. If it would have been more complicated, I would have paid someone else to do it. I’ll still have a professional come for the annual service contract.
    Thanks a bunch including all the extra notes and ideas.

    Geez, the “temperatures dropped to the 50’s and we quickly changed our mind”! Wow! It must be nice, lol! Here in Maine, if it’s in the 50’s we don’t even turn the heat on!

    Thanks for the tip! Nice to see that many years later this post is still providing a lot of value.

    Took 3 o4 tries to get mine bled well. I have new found respect for my oil repair guy. He usually gets it right away and in about 8 oz of oil!

    Ray,

    Thank you so much for your thorough breakdown of what to do! I am a first time home buyer with a 2.5 year old son and this did the trick! We ran out of oil yesterday afternoon, and I put some OTR Diesel in to get us going (It was sunday and monday is a holiday, so we’ll be on diesel for a couple of days). I couldn’t get it to fire but I knew fuel was in the lines. I work as an HVAC sales person, but I know so very little about oil.. it’s not something my company sells. Point being, I know what rate the service tech’s comnpanies charge per hour and it’s a travesty what companies charge (the techs deserve good money for coming out in the middle of the night, don’t get me wrong.. companies gouge homeowners and don’t pay tech what they truly deserve). I’d much rather be able to fix my furnace on my own, and with your help I’ve done it! Thank you so much!

    I saw someone is this post who used the outer casing of an extension cord since they did not have a 1/4 tube, which I thought was resourceful.
    I was in the same situation but a quick scan of my basement I saw a box of old toys destined for a yard sale or the dump. On the top was a teapot, the spout fit perfectly over the bleeder valve and the curve of the spout directed the oil into the teapot without splashing.
    It would have worked nicely to pour the oil back into the fill pipe of the tank but it was so nasty I disposed of it in accordance with all local regulations.
    Looks like your “40 second” reset tip has saved many people the expense of a service call.

    Thank you so much for this advice. I stupidly tried to wait until oil prices came down…..and ran out. Once the tank was filled I tried to re-set the lock-out with no success. I put a search in for how to prime an oil boiler after you’ve been stupid enough to let it run out and found your site :-)
    Before I bled the system I thought I’d try holding the lock-out switch for 40 seconds. It took 2 attempts but I now have a working boiler thanks to you :-)

    Worked like a charm. Trying to milk what oil was left for payday…NOW I will never let my heating oil run dry again.

    My weekend project. Put me on the list of people who let my oil run out. Ran out last April and made it this long before filling. Was hoping 100 gallons would do the trick. It didn’t. I’m hopeful and handier then most. I can do this. I’ve been unemployed for almost 4 years. Can’t call a serviceman… that’s food on the table.. ya know? I’ll let you know how it goes.

    Last time I called for service was over $400. I thought I’d be smart and block the vents in rooms I didn’t need to heat. YOU CAN’T DO THAT WITH AN OIL FURNACE… it’s too hot, it has to exhaust, or it overheats and you break things. Silly me!

    You are the master. Thank you so much! It worked, I have heat. Tubing cost $.70 including sales tax. Had to do it 3 times. At first it came out all pink and foamy… I’ve gotta think that’s oil/air mix from having air in the line. When it cleared up it ran great. So relieved knowing I need not fear the weather this year. THANK YOU! You saved me a pile of money I’m sure.

    Quite late to the party… I’d add a few points:

    The location of the bleed valve will vary by manufacturer. Research this in advance or have your service technician show you where it is during the annual maintenance.

    Don’t add the oil back to the tank. It likely has some sludge and/or other contaminants unless you carefully washed the container first. Dispose of it in a safe manner (burning it a little at a time, outside, in a can of cotton rags is effective)

  96. Meri
    December 27, 2012

    I did everything you said and the heater came on and ran most of the night. Around 5:30 am it stopped I went down and hit the reset button and it started but some smoke came off the motor area, I turned it off, should I bleed it again or is something else wrong?

    Well, God Bless YOU!!! years later and you are still helping the inept with trivial, yet expensive DIY projects! Whew! I am a recent widow whom was blessed enough to have a truly gifted husband when it came to these little tasks that I so vainly took for granted. Now, embarking on my lonely trip through the remainder of my life, I continue to stumble my way through things like figuring out how to change a light bulb in socket that is 20 some feet in the air….and replacing the broken chain on the toilet tank so i can flush without manually pulling up the stopper….ugh! what do ya know….oil tank empty = no hot water….oil tank full = no hot water….hmmmm. Thank God I found you!! I am going home tonight to try this trick out and see if I can DIY all the way to the bank because I DIDN’T have to call the expensive furnace guy. THanks so much. I will keep you posted. :-)

    Hey Ray! I tried to prime my oil tank following a few instructions online. Yours was by far the most helpful. Thanks! My house is finally warming up after two Vermont days in February without oil!

    Hey There! I just lost my job as a computer consultant and my fiance have been trying to conserve every dollar we can. We rent a house – and the cost of rent and all utilities and to add oil? OMG – oil prices are RIDUCULOUS! So we run our oil tank down to the last gallon usually. I am pretty good with getting oil delivered right when it hits “E”, but this time, I woke up today to find that the furnace had turned off. I am a very hand guy – used to do plumbing, electrical, and carpentry work at my old house I owned. Furnace work was always left to the repair guys. But when I knew I ran dry, and had to prime the pump, I cringed at how much it would cost. Your article saved me God knows how much in a house call! Thanks for the info. Really easy to do, once tried. Once thing I was wondering is if I should have held the reset button for the 35 or so seconds before I primed it. I had to hit the reset button about 5 times to get the flow before closing the bleeder valve. Then I held it for 35 seconds, and the ignitor blaster and the puppy started. I am wondering if I had held the reset button for 35 seconds at the beginning if it would have fired up without the priming? Who knows. Regardless, your infor helped me a lot! Thanks!

    Thanks Ray for the help. I too ran out after trying to conserve the 22 gallons of diesel i added myself, which the Oil Co. Sugested since their min was 100 gal ($500). After I found and opened the bleeder valve I used a plastic water bottle to capture the oil after depressing the set button. It sputtered couple times then ran solid before the reset popped up. That was actually good timing because the bottle started to get full and gave me a chance to close the bleeder screw. Ran fine for the last half hour tonight to get the house from 57 to 60 which doesn’t seem like a lot but was definitely noticeable. It will be great to wake to 65 instead of 53. Scott in Seattle

    Ray, Thanks so so much for your knowledge!Let my oil tank run out over the holiday weekend. Had 244 gallons filled… And was still having a problem.. I am the worst DIY handyman in the world, yet after following your directions.. and less than 5 minutes later….. I was taking a HOT SHOWER!! Thanks for making my day… Thanks for saving me a headache and $$$…

    Greatly Appreciated!

    question: i’ve seen plumbers bleed the furnace for many years, this time my son and i did it and this was the first time i had seen a creamy looking sludge, then turned pink….why is that? anyway, after few attempts, the furnace worked.

  108. jose Sevilla

    If your tank is underground then it looks like your tanks has a leak and water is getting in. It happen to ours which I put up with for 2 years before installing an above ground tank. Water keep shutting off the heat every time it rained , so I placed a large tarp on the grass to limit the amount of water. Didn’t help much.
