    Hi
    Our fridge in our 2004 Motorhome is not working on Gas.
    Dometic 7655L
    Fridge/Freezer works on 12volts and Elec.
    Freezer works on Gas but the Fridge wont.
    We had it serviced in May and since then we have a problem.
    We took it to a dealer and he replace a solenoid but it still wont work when we got it home.
    Any help will be appreciated.

    Thanks in advance.

    Sounds like it needs a good shake up to clear an air lock. Good luck.

    Hi, Roger sounds spot on,you will have to remove the f/f lay it down for a bit then stand back up and re-fit :thumb:

    I don't quite understand if the fridge works on mains and 12volt it surely means that the refridgerant is circulating so theoretically it should work on gas :Confused::Confused:

    It's just the heat source that is changing check the flame is not too low or too fierce if you can get to the back of the fridge from outside perhaps a little bit of rust has dropped down onto the gas jet, worth a look I'd say.:thumb:

    Best of luck.

    Regards Pat

    Happened to me on my last M/home, cleaned the jet and WHEEEEEEEEEEEE off it went. I also had a fridge stop working, phoned a local chap and he advised taking the fridge out , turning it upside down and leaving overnight. Did that and WHEEEEEEEEEEE that one worked too :Smile:

    just a thought, the fridge is level isn't it?
    Motorhome not parked on a steep slope?

    We took it out and gave it a good shake and then left it laying down for a couple of hours then we refit it and put it back on Gas this morning. Its getting cool but nothing like our house fridge. Flames seems to be fine. Hubby gave it a good clean out.

    Wildman.
    Yes it is level. :Smile:

    What we cannot understand is that the freezer is working fine on Gas but the fridge is not.

    Thank again to all who helped.

    We had the same effect with the same fridge.

    The f/f worked fine on 12v and 230v but although the gas flame looked fine the fridge wasn't getting cold. The problem turned out to be the chimney was badly sooted up from using a Spanish Repsol bottle which had been laid on it's side in transit (apparently they put oil in the bottle to prevent rusting I was told). The heat from the gas flame wasn't reaching the exchanger whereas the heat from the 12v and 230v elements being next to the exchanger was o.k.

    To rectify we had to remove the fridge to get at the top of the chimney then remove the spiral which is hanging in the chimney and give it a good clean, at the same time remove the burner assembly from the bottom of the chimney. Clean the chimney through (abrasive paper wound round and taped to a bamboo rod did the trick). - what a soot fall we had. Reassemble and hopefully Robert is your fathers brother.

    Good luck with it!

    Don't like to criticise. Reason we won't bring it back to service man.
    He serviced boiler and fridge. He replace a board in Boiler £120 sterling.
    We had left it to him for 3 hours and when we returned it was ready. His charge was €560 Euro. He is the only Truma serviceman here in Southern Ireland. Needless to say we were not happy. Our Motto next time "If its not broken don't fix it

    Thanks to all who replied.

    We took burner apart again today for the 3 time +.

    We got air hose and blew it out, The flame seems to be higher now.

    Now my question : How high should the flame be, some say 30 to 35mm.
    Is this OK?
    How do you turn flame up and down?
