    I hope some fridge experts may be able to help me; my fridge (electrolux in a 1991 Hymer 54 has never really run on gas, I have been able to get the pilot to light and stay on all night before, but the piezo started clicking as soon as I turned it up to cool.

    I can't get any of the local service agents to call me back so I have taken the access panel off at the back and had a look myself. I've given it all a bit of a clean up and it sparks and lights ok, but after a while the flame seems to come out of a hole in the side of the burner indicated with the red arrow below. Do I just replace the whole unit? should the nut (green arrow) just unscrew? it's very stiff and I am a bit concerned about damaging the gas pipe.

    You need 2 spanners....one for the back nut on the gas inlet (green arrow), and the other to grip fast the square section (red arrow) of the burner assembly. That joint is always stiff.
    Once you break the joint, the pressed metal jet may fall out, or more likely, will be lightly held in the burner assembly. It all wants a damn good clean, and don't forget to clean the flue.

    if you do clean the assembly, don't poke the jet with any wires etc.best to blow it all out with a can of compressed air, like the ones used to clean computers (£1 from poundland)(y)

    sounds like a partially blocked gas jet. at that age i would fit a new one due to likely corrosion. as said the flame is never bigger than a pilot light

    another issue is the flame failure thermocouple may also be corroded best change both whilst the fridge is out

    Thanks for your replies! I have put a drop of penetrating oil on the nut and then spent the afternoon washing the van (c:

    I will have another look tomorrow.

    The thermocouple looks to be ok, some of the insulation from the spark plug lead has been damaged where the flame "backfired" but is giving a good fat spark.

    I will be SO happy if I can get this working!

    It does as that is how it works on gas.
    I've got a 27 year old T800 & the gas flame definitely gets bigger as the temperature knob is turned colder. You can watch it through the viewing window.
    On mine you turn knob & hold in whilst pressing igniter to light . Once alight rotating the knob from minimum to maximum increases the gas flow as it is a tapered valve with a flute in to allow more gas. That is how they work ; max setting = tiny flame ; minimum setting = large flame.

    On older fridges you 'dialled' in the temp of the fridge with small flame icon...up to large flame icon, that flame did vary in intensity, but there was no thermostat to control the temp of the fridge, and the flame was on permamently. On newer fridges (poss early 90's onwards, but not too sure) there is a thermostat to control the temp in the fridge, the flame intensity does not alter, the thermostat turns off the flame and re-ignites when the fridge temp rises.

    You still need to clean it though.

    Well... disassembled (again), bashed all the crud off by tapping on the side of a lump hammer until nothing more fell off, blew through with a compressed air (as much as my lungs would compress it...) and reassembled. Lights first click and burns with a steady blue flame! I have put an ice cube bag in the freezer and will give it an hour or so to see whether it cools. Very excited!

    sometimes you get piles of rust and crud out when you service a fridge. especially if it hasn't been touched in a few years

    Make sure you have a carbon monoxide alarm .... my fridge was giving off dangerous fumes last year and my alarm may have saved my life. Got the Dometic people out at one of the shows and they cleaned out load of gunge for me.

    I have got a CO alarm... admittedly it is in the "man drawer" in the Welsh dresser, but that is largely because I didn't have any working gas appliances! Having fixed the fridge AND the Truma space heater (get me) I shall now install it, possibly even with a back up because I guess the fridge will be on all the time when parked.

    It has been done!

    I suppose to many switching the fridge to gas is just second nature, but this is my second MoHo that the fridge hasn't worked on gas (from a boating background gas is just a no-no) and I can't put into words how pleased I am that I have fixed this by taking it apart and banging the relevant bits on a big hammer; no big outlay of cash.

    I feel a whole world of wild camping and aires WITH cold beer opening up to me... :cool:

    As you're talking fridges, can this be done via the rear vent or do you need to remove the fridge?
    (Dometic 76 something or other in a 08 elddis 100)

    I can't comment on the Elddis 100, but my old Hymer has an aluminium plate just below the rear light cluster which can be removed for access.

    I would be quite surprised if the fridge had to be removed to service the burner, especially as the burner needs to be sealed off from the habitation, so I would imagine that it can be done via a vent or similar...

    I hate to disagree but on my (old) fridge this is NOT correct...

    On mine (1987) the flame is NOT a pilot light and it does go higher or lower as you adjust its level on the dial on the front.

    Anyhow... the OP has it sorted now...

    With gas flames... like with football teams... blue is GOOD... any other colour is bad (especially yellow).
