Guide to repair / fix / diagnose / troubleshoot oil burner or oil boiler

[@bllt9]

Your info on the solenoid was spot on. My oil burner was only burning for a few minutes and then turned off, replaced the solenoid and everything is working normal. Thank you a lot, your info helped me a lot, especially because it's -20C here right now 😅😅

[@daizyflower272]

Well spoken, well presented, and very professional. If only there were more people like you!

[@vapoureyes]

The best video on KZbin regarding explaining problems with burner . Thanks for making it .

[@ev2power415]

Thank you so much for doing a great video. Might have been made seven years ago but still totally valid. Really clear and pitched at just the right levels for those who are happy to try and fix things themselves but just need that insight into how things like this work.

[@tomking5855]

Excellent summary of burner operation and trouble-shooting. Thank you.

[@alexmatthews2193]

This short video is perfect for people who have some idea but were a little scared of fiddling. Just a shout out for fixing my boiler today bro! Thanks!

[@troywoolacott7398]

On the coldest day of the year. 4 hours of servicing fault eliminating provided no solution. I had a tea break and found your video (after watching 6 others). Your tip about the pump solenoid failing after 2 minutes due to dodgy coil heating up and breaking contact . Swapped it from my boiler spares box and great joy we are warm again. Many thanks excellent explanation well done.

[@michaelbryant2383]

Very helpful, many thanks! As a gas boiler specialist who's just bought a house with an oil boiler, this has filled in quite a few blanks about oil boilers for me.

[@brucecurrie6913]

Very helpful primer in sorting out oil boiler problems - for someone keen to learn the basics. Thanks ,Sebastian, for posting!

[@ventureIntro]

Sebastian, thank you for the knowledge. Obsolete oli burner for rayburn, exhausted all avenues, but your point on the solenoids saved the day! Nonlonger shivering. £10 beer tocken/tip sent as a thank you. Cheers

Magic eye is a photocell just so people know what to look for at the merchants. Transformer produces 30 to 50 thousand volts for ignition of the atomomised fuel/air mixture but with a low amperage so it is less lightly to seriously harm or kill. The 220 to 240 volt supply to burner is much more dangerous as it can have anywhere from 0.1 milliamps amps and 3 amps can be enough to light up your insides and youd be history. It takes only 100mA to stop your heart. It's a good video guide and I'll recommend it for others to watch👍 Always replace bearings. Solenoid coil slips over the brass solenoid valve stem. Depending on the size of the jet....psi for diesel is 140 psi and 90 psi upwards for kerosene.

[@derfeluk]

Brilliant video, fixed my Rayburn 440 by replacing the oil pump solenoid, had one lying around in the "stores". Saved me a Christmas and Covid call out! Stay safe and thanks again!

[@AlanFM900]

Great vid , helped diagnose the fault on my boiler , now up and running again . Thank you.

[@stephensmyth6363]

Best vid on troubleshooting I've seen

[@jonnyanderson1778]

Thank you for the video... mine was starting and stopping after a few minutes.. I needed the coil on the fuel pump... got it going just in time for Christmas ... thank you again

[@dronenut6359]

I'm considering doing an oil boiler maintenance course. I didn't have a clue what they were about but this video gave me an understanding. Thanks for sharing.

[@martinaddison6244]

I have my OFTEC certification tomorrow, watching this is a good refresher and confidence builder so thanks.

[@STurner-SLOBS]

Best oil burner video...one more fault symptom...the oil pump drive adaptor can wear out, worth looking at.

[@petroskaneas1880]

The best analysis of burner problems and solutions .

[@ventureIntro]

Really appreciated, great video. Solenoid diagnosis sounds exactly what's been driving me mad....will investigate, thanks for the steer and know how!

[@kierangcollins]

Best video on this topic by miles. Just fixed my boiler thanks to you!

[@stevebrady3634]

Spot on! Exactly what I needed. Clear troubleshooting advice which led me to the problem with my boiler. Turned out to be an easy fix thanks to Sebastian Hibbert. I watched at least 5 other videos (very little to no help) before I found this one. Thank you!

[@ernest-pj2du]

Very well explained, will save for a reference in the future .

[@MDINAITALIA]

Cheers Sebastian! A new starter capacitor got my old Myson Velaire going again! It just has to hang in for a few more weeks before we get our new boiler.

[@FrenchiePete2]

Top man well done, just cleaning the internal oil pump filter has saved me a fortune, thank you so much

[@larydrain]

Very useful video, especially late at night when all the engineers are in bed. This helped me to get my burner running again ( jammed fan blade )Thank you very much for sharing your knowledge.

[@instalism]

Thank you so much.Really excellent complete comprehensive guide.And also in really excellent english.Very well done.

[@johnocallaghan7830]

Thanks very helpfull! It would appear I had a problem with a clogged up oil pump filter and a dirty photocell sensor. The burner is now back up and running nicely thanks to your guide!

[@johnbehan2757]

Thank you so much got my boiler sorted such a clear explanation and troubleshoot I'm really grateful 👍

[@davidhenderson1073]

A good lot of common sense and info in there Sebastian, thanks for sharing.

[@varnasvarnas7149]

Very informative, no wasted time. Perfect.

[@jetblack11td]

Hello Sabastian... All credit to you.... A very good video.... you do explain things well in terms the average Joe with a bit of common sense could follow... and you do make the points about safety and not playing with the air/fuel mixture! All the Best.....Trevor

[@steveraw8234]

Hi Been having trouble with my heatslave 26/32 Having watched your video I tried a few of your tips, and found the fan wasn't turning freely (by the way this was on a sterling 40 burner) so I disconnected the fuel pump from the fan and the fan was fine but the fuel pump was notchey so put some olive oil into the bearing side and Worked fine. So ordering a new fuel pump Original symptoms were when flat cold And everything reset it would heat up ok Then when you wanted more water i.e. Shower/bath /heating etc it would trip out Guessing the bearings in the pump when warm would be more tight Thanks for the great video although different pump the principles are the same 🤗🤗🤗🤗🤗

[@RaleafBarsind1]

The baby solenoid was the problem for me! Thanks!

[@ZKRITTEX]

I salute you sir. You have teach me a lot today. Very very informative. You deserve more likes.

[@jamesbarty4931]

Useful video, much appreciated pal. Very informative no time wasting or talking rubbish

[@zerovehicle]

Has the principles right. It helped me a lot to understand my possible problems. Thank you

[@fireboyandy]

This video provided the info I needed to fix my problem, Thanks!!!

[@auzworld]

Really well explained...possible faults that are in order... well made video !! thanks

[@michaelchare7119]

Excellent video. Found my boiler stops because the coil goes open circuit when it gets hot. The resistance was within spec when it was cold!

[@peterbutton-yi7wp]

Great information. Followed your steps needed new condenser easy to replace all working again. Many thanks

[@stuffoflardohfortheloveof]

Very interesting. Thank you so much for taking the time and effort to provide this. 👍

[@mikewinstone7361]

Fab bit of knowledge wish I had watched this would have saved me time

[@philipwatkins8157]

Bloody excellent - I've got a Redfyre Oil Range Cooker - can I get someone to service it; more chance of finding Hen's teeth! Last engineer recommended I buy a new range cooker (£9k).

[@buttyboy100]

Ditto, my 20 year old Redfyre hasn't been serviced for a few years for that very reason. Local oil boiler service people seem to imply it is some kind of black magic.I think they just don't like having to work through the relatively restricted front panel of the cooker. Most common problems on mine have been solenoid, several times (Grundfoss solenoids seem very unreliable) and the motor capacitor changed a couple of times. This video has been an excellent explanation of what is going on.

[@AndyCindrey]

Super helpful and informative, thank you 👍🏻

[@AndrewMeadan]

Very informative thank you. Could you also tell me after a an Electro Oil Sterling burner has been run out of fuel why the restart button refuses to iluminate, to allow a restart to activate please?

[@charleswymer7934]

Very informative, thanks for sharing your knowledge.

[@steveincork3669]

Great Video especially for young Oftec Entrants.

[@mightymagnum8811]

This was very helpful, although I often wonder why they go to the bother of creating such sophisticated equipment to operate an electric chair, if a simple dig from a central heating boiler is all you need 🙂

[@SK-tj3yy]

Very helpful presentation. Thank you Sebastian.

[@medicine_man_sam]

Fantastic video mate. Fully understand my boiler now. 🤟

[@uber-wagon]

Fantastic video and excellently explained, thank you.

[@colinsmith9126]

Very helpful guide for fault finding.

[@williammoore2708]

thanks for the info was able to fix my burner myself & save myself some money

[@p.macdermott2490]

Very good instructional video. You mentioned a wet nozzle means " not atomising properly How do I remedy that problem? Is it an oil pressure issue?.

[@lumay333]

Thanks for great video. My control box has not got any light on but the pump wouldn't switch to heat water or run central heating. Can I still press it to try reset it?

[@chrisbush8410]

Brilliant video and extremely well explained! I watched it through a few times while waiting for a qualified engineer to come to fix my Rayburn 680k cd boiler as the cooking side kept locking out and eventually would not fire up I'm surprised how simple the workings are in oil fired burners and how easy they are to understand having watched this video It turned out that there were 2 problems which were preventing my burner to fire up First of all, the oil pump was jamming, not all the time, but intermittently. the oil pump and solenoid were replaced and the burner fired up However,after a short while it locked out again so the engineer came back to it The second time, he replaced the fan capacitor and that has sorted out the problem I will continue to get my Rayburn serviced annually by the same qualified engineer but I was just curious as to what the function of the fan capacitor is, which is the only thing that wasn't explained in any detail in this video Can anyone tell me please?

[@martinaddison6244]

I have been servicing around 20 oil boilers a week and attending on average 5 breakdowns a week for the best part of a year. I personally don't find oil burners 'easy' at all!

[@duffermod1]

Hi Sebastian. My burner won't come on at in house control unit but when I go out the red light is on, so press it, but funny thing is it works and STAYS on but when I switch it off indoors it won't come on with the timer , goes back to red light 🤔 . In June I cleaned the actual boiler and cleaned the plates inside and changed the nozzle and was working fine until a couple of days ago any help would be appreciated

[@miketrippas4036]

Many thanks for helpful Info, solenoid replaced job done.👍👍

[@thetruth156real3]

Great video, already fixed mine, wish I had found this first.👍

[@Robertscr20021]

Thanks for this video, helped me fault find my Stanley Super Star Aga

[@fionnan2811happy]

The drive pin for the gears in the pump can break causing no oil pressure. I get them pins made up so I can easily replace them. Or fit a new pump and recondition the old one and it can come in handy

[@andymav3023]

Hey still learning oil burners what’s the best way to know if water has gotten into the pump

[@gallilao0111]

[@roryt4039]

I have a burner that fires up for a few hours then locks out. I have changed oil pump and solenoid. Do you think it could be control box

[@samdeberry3348]

Hi Sebastian, Great video. My boiler seems to light but cut out when the air temperature drops. Any ideas?

[@Mrgeorgeymc]

Very clear and concise tks

[@joedakin5160]

Great video 👍

[@HumanProgramming]

Hello Sebastian, I'm struggling with a Bairan in a bakery oven, can you help? I got it to spray diesel and other fixes but it's just not flaming up.....a very small flame comes on and struggles....yet the fan is blowing very high and the sparks look good and strong......I even changed from diesel to kerosene but it's no use. HELPPP

[@sameradem]

I have ecoflam minor 4.1 with nozzle 0.5. Any recommendation on what air flow setting?

[@indianatone218]

What do you think problem is when it does fire up then dies after 30 seconds roughly .i have to wait a minute till I hear a click from pump then I press button on pump it fires up then runs ok ,do you think it's air in line ? It doesent work from the control unit in the house ,I have to go out and start it from the unit outside .would appreciate your input .

[@henrybartlett1986]

Very useful. Many thanks.

[@mariafitzgerald4277]

Hi very interesting, but I'm still stuck where do I find the bleed nut on a ecoflam boiler. The boiler is very old but it was working fine until until a friend house sittin ran out of oil. It will strike up but won't stay on I think it could be air in the line. It's a ecloflam boiler with a flair motor. Any help would be much appreciated. Maria.

[@MizunoIronMan]

Really informative thanks.

[@johnrmce]

What about if I changed the solenoid nozzle and photo cell but now its still cutting out with lots of white smoke and ignites and goes out until it just cuts out, its a nu way burner? thank you

[@jmcguire5151]

Great video. But I ran through mine and everything worked, but it still won't pump fuel.

[@michaellyle8673]

Great help mate.Cheers.

[@briancunniffe3417]

Hi Sebastian, can I ask your advice please. I am working on a monoflame minor 1, it’s not even attempting to fire, fan/motor doesn’t come on, I have wired motor to mains and it works, when I power up burner it just sparks electrodes briefly but no motor running. I’m thinking it’s control box, any idea what might be wrong? Thanks, Brian

[@ashleythom1052]

Useful but didn't really cover "no spark" when ignitors are OK

[@sssttt6533]

Very very very great video

[@billtyler2386]

great video

[@aymandaraghmah7743]

I started the burner, with no diesel left in tank, now it's not working, any suggestions?

[@haqkomano4175]

when I on my heating system the light of controller within second gets on then goes off then no light is there the orange light stays on when its working and flame is working properly but in this case, it is not igniting anymore, what do you think what it could be? Please reply because I am going to open it today the first time in my life, that would be very kind if you help us. thanks, yesterday I pushed the button and it went on but today goes off.

Hey man I'm working on one of these at the moment and it's cutting off with a click what can be the problem do you think

[@cassandracurse7065]

very good instruction

[@davidlisney2059]

High voltage, combustible gases and moving parts, that ticks all the right boxes!

[@elitefleet6402]

Hi i have a problem with mine and no one can seem to find the problem. It did fire up an run then the red flame light came on. now it might start up, might not sometimes. when it does it can run for 1 to 5 min then stop it might start up again then it might not. HELP

[@pauls466]

in case it has a oil pre heater it can take a while before it starts
