Fridge not working on gas, can anyone help?

hi
i had trouble with mine. i pulled the fridge outand extended the gas pipe
with some tube so i could see the flame with the cover removed. the flame
looked a bit small even after cleaning so i removed the jet and cleaned the
burner behind where the jet sits it was rusty. i fitted a new jet cost £8
the flame seemed to be a lot larger. it could have been a different size jet
though because i dont know what model fridge it is no numbers. while i had it
out i fitted a small fan to the fins on the back to help ventilation. there was a
vent on the back of the van under the rear light not being used so i opened
it up a fitted a grille, it works perfect now even without the fan. last month
i had it turned to no 2 on the controller and it was still 4 deg c

Thank you. I've looked at the jet, how on earth do you remove to insert a replacement? M

Thank you.

On my model there is one dial to regulate the temperature, whatever the source of energy. That works for 240v and 12v but has no visible eefect on gas.

Please explain what you mean by "double check the jet feed from the gas feed pipe" - what should I be checking?

Hi,What i mean by double check is do it again,undo the nut holding the gas feed to the burner exposing the jet,I poke fine wire down the jet,I can hear members shrieking in disbelief but it works for me.Also your dial that controls temperature should still turn the flame up or down when you have selected it to gas.If the jet is 100% clear then it must be the temperature dial.
 
Stuck a new burner (£45) in mine and gave it all a good clean out. Worked a treat afterwards.

hi
you have to prise it out with a pointy tool it damages it in the process
it is very thin. the new one will push in with the pipe fitting after you
have placed it in posistion.

It sounds like you should take it to an expert as you could do more harm than good. It's dangerous to mess about with gas appliances.
 
hi
there is at least two different burners fitted that i have seen.

Thank you to everybody for your help & advice.

I had a spare gas jet and fitted it, also cleaned out the burner. Gas lights with no delay but doesn't respond in any way to the temperature dial on the front of the fridge.

I've opened up the Electronic Component Assembly (pcb) and find that the temperature shaft offers no resistance because it's is not attached. It doesn't look as though it's broken off, though, both the end of the shaft and the component are smooth.

What am I missing here? Is the shaft meant to fit in the pcb, or what?

Do I need to buy a new pcb & a new shaft?

Finally (2nd image), on removing the pcb an unattached cable was revealed. I can find no connection for it anywhere. Is it a standard but redundant cable?

Michael it looks as if the shaft has sheared off in the variable resistor may be it was stepped down in diameter at that point can you get the bit of shaft out. It looks like ordering a new shaft.
Perhaps the knob had been overturned the wrong way and sheared the shaft

Drill a hole into the broken spindle. You should then be able to screw a self-tapper into that hole and then hopefully give you something to pull with pliers. Failing that it will be a standard potentiometer so anyone with a soldering iron should be able to replace it :D

I would try anything to get it out, if the only alternative is to replace the PCB then you have nothing to lose if you break it

Thanks everybody. I would have followed your advice to drill out the broken shaft but, my only accident of the day, one of the springs behind the selector switch dropped down the plug hole. I know, I know! I'm kicking myself! M

More than two sorts of burner. But only one type of jet. Not all the same size hole, of course.

hi
when you said the jet unscrews with two 11mm spanners did you not
mean the burner. because on mine after you unscrew the burner with
two 11mm spanners you have to prise out the jet from behind the pipe
fitting. but looking at the op photo it is different to mine as i dont have
the cicut boards.
 
hairydog said:
No, on the ones I've looked at, you don't need to touch the burner to remove the jet. There is a space between the jet and the burner, big enough to remove the jet.
Sounds like what you are looking at is very different.
This is a picture I found on the web, and although it is reversed L-R compared to most of the ones I've seen, this is how they look, and this picture is annotated. They call the jet the "orifice".

The RVM7631 has this type of burner, it is the one that eddyt is referring to where you unscrew the pipe with a 11mm spanner then prize the jet out

I've not seen one like that.

It doesn't look as if it is made of stainless steel. Wonder how long it will last?

I had a search. Seems it is an RM7361

Sorry it was a mis-type, I meant RM7361, I gave him a link to the parts earlier.
They are not made from stainless steel, I changed my burner assembly last year because it was rusty and the rust particles kept blocking the jet, it was 14yrs old by that time

It is much the same as the one that I replaced and a similar age.
