no power to oil burner

kend805

since the hot weather arrived i have not needed to use my heating but went to turn it on today and there is no power going to it..(red reset light is not on)

all trip switches are up so i am lost ...any ideas?

.243

either the thermostat on your boiler has tripped out,or you have a wall stat in the house turned down too low

kend805

wall stats are both up to normal temp 25 degrees..how do i know the thermostat is tripped and how do i reset it.. it is making a really really low sound as if its on but the light is still off

turn both wall stats up full,the stat on the boiler has a small grommet beside the dial (make sure the dial is not set too high) unscrew the grommet and press the small spring loaded button inside

That low noise you are hearing is the circulating pump so power is present. Has the pressure dropped on the system? There might be a pressure gauge somewhere on the system at the boiler or in the hotpress.

kend805

@.243... the stat on the boiler is at 3.5 and the only thing to unscrew is the screw to adjust the dial.. is this what you mean as the grommet.

@johnniek.. the pressure gauge reads 0 but if i switch on the heating it rises to 25 psi and has stayed at that pressure since i switched it back off..(approx half an hour now)

Is there any way you could post a pic of the boiler

cant get a picture to upload but thats what it looks like

jimmyw

Did you try resetting the boiler itself.There is a button on the boiler.

Oh you said the reset button/light is not on.Have you a switch on the wall with a light ? (main)

the high limit stat is behind the black knob
unscrew it off and push the button

kend805

switched on at the mains

hit that reset button but still nothing

jimmyw

Try to see if there is a firevalve near your burner, it might have been tripped.It happened to me the other day after we had our summer;).

thread here similar too.

i looked at that other thread and the pictures are the same as mine except i have no red valve near my boiler only the reset button which you circled blue in the pictures,, not sure what you mean about firevalve either

If you have a look on that other thread,you will see what I have anyway.Its a valve to shut off the fuel flow if there is a fire, so it should be somewhere on the line from the tank to the burner.Of course it may vary from model to model.Its a possibility anyway.

The way I reset it is to pull up on the valve, reset at the burner and viola! off she pops.(make sure there is power going to the burner first)

So you should have 3 resets, one inside the burner housing (Thermostat), one on the burner, the firevalve.

Billy Bunting

If the red reset button on the burner is not lite then you have no power getting to the burner, forget the fire valve. If the pump is running and you have pushed the reset on the high limit stat and still have nothing then you need a service call, i suggest an Oftec registered Engineer is the way to go.

As for the other thread that run for some time on the Appliances forum, if the OP of that thread had posted it here, or indeed the Mod had moved it here, then the OP would have had the right people reading it and may of saved themselves that service call.

JohnnieK

The burner reset light is not on so I doubt it's a fuel problem. It needs to be determined first it the dual stat is receiving power or not, could be just a loose connection or maybe the burner control box is knackered.

Is the burner running for a few seconds and then shutting off OP? but if its not running, then you're right, it not the FV.

I did think that other thread should be here too, but I wouldnt be bad mouthing the mods if I were you billy:D

Just stating the obvious, Mods move topics to relevent forums, and as the Mod concerned stated 2 days ago that

Unless you know what you're doing, leave this to the technicians who have been trained in working on the burners

then the obvious move was for the Mod to move it here. :rolleyes:

You're right, I know they do.I was only joking, don't get offended.;)

jimmyw

All you can do OP is see if all that can be reset is, other than that a technician is in order.

@jimmy... found the valve and it looks exactly like your pic in the other thread but mine wont lift up at all and i dont want to adjust it..i can still hear the fan running when power is on and i tried the other 2 reset buttons ie. the red one on the burner and the one at the thermostat which is in my hotpress.. maybe its time for a phonecall

Is it close to the burner? If its the same, then it has to be pulled out if its not out already which it could be.Try to see can you push it in, if you can then its already out and thats not the problem.When mine was on, the pump was still going and the lights on the control panel were lit, so I assumed the heating was on util I touched the rads to find them cold.

kend805

yes its just beside the burner but it does not move in or out, also the burner does not evn attempt to start up,,the only noise is that of the fan,
all wires look to be ok but i am no expert so will leave it up to one..

thanks everyone for trying to help

You have not mentioned the FAN is running before now, it was presumed that it was the circulating pump you could hear and you went along with that.
If you’re now saying that the FAN is running then that’s a completely different scenario and as your burner is an RDB then i would look at replacing the photocell.

can you explain what the photocell is please

Billy Bunting

Please make it clear, the humming noise you hear is coming from the burner (red box attached to bottom of the boiler) or is it on the heating system ???

DGOBS

If the burner was humming it would run to lock out, the fan on in constant pre-purge is
a pe cell
b solenoid
c control box

If a RDB has a faulty pe cell then it will not always go to lock out, we've had this discusion in the past.

Exactly as I said, a pe cell can cause constant pre purge!

But if the burner was 'humming' it would suggest a failed pump or fault capacitor (motor on the outside) and would run to lockout

Billy Bunting

Sorry DGOBS, the original notification email i recieved of your reply read

You either edited your post shortly after the post or the notification system is bucked, anyway, my reply was in responce to that email.

And i also read the OP posts as the humming noise was the fan running as in their previous post.

kend805

the humming noise is not coming from the burner but from the heating system.. it sounds louder when i stand beside the exhaust vent at the rear of the unit

Your Hi-Limit stat will not be located in your Hot Press this is more likely your cylinder stat.

The Hi-Limit stat is located on the boiler( as opposed to the Burner) itself, and is normally a Grey or Orange box with a dial and a small cover screw.

Like This....

If you can locate it remove the small black cover and press the concealed button below.

If this doesn't work your best bet is make that call.....

Sorry but you are clearly lost with this problem and have no clue of even the simplest things on your system, i really would suggest you get your local oftec tech in to have a look rather than us start to explain how to open this and that and test for live cables, i really wouldnt like to see the priest have to call.

DGOBS

+1 Billy

For us to guide you, you really do need to already have some basic knowledge

kend805

found the boiler hi limit stat but there is no black covered screw only the dial.. and yes lad i have not got a clue about the system whatsoever but cheers for the help anyway.. will post the results when the priest calls ..

thanks

is it like this

the black knob unscrews to reveal a button that needs to be pushed firmly in to reset

Thank you for this post, worked a treat pressing reset on high limit, needed heat tonight!
