    :(I've been away for over 2 weeks now and the fridge has been working on a mixture of gas and electric without any problems. The last week purely on gas. Noticed yesterday that it didn't seem as cold so turned it up. Got up this morning and the fridge is no longer cold and everything has defrosted in the freezer.
    Any ideas would be gratefully received

    This will probably sound bonkers, but mine sometimes doesn't work the colder I try to set it, might be interesting to turn it to a half way setting and see if it improves (y), although I don't think mine has ever actually defrosted

    Have you still got your vent covers on Clive? That would make the fridge less efficient at this time of year. We have also found that when the weather is warm the fridge works better if turned down rather than up.

    Two suggestions

    Remove external winter vent covers if fitted

    Is the van level?
    Needs to be within 6 degrees if level or the coolant can't circulate

    Hope this helps

    I had that problem last summer in France. Spent a couple of hours on an aire, dismantling the burner and cleaning the jet, then all was fine.
    (Don't poke anything through the jet - just blow it and brush away any soot.

    When the weather is very warm, you'll find there is a sweet spot for your flame . Turning it high on max cooling can often result in it warming up. Turn it down a notch and experiment to find that sweet (coldest) spot on the dial. Sounds crazy but it works.

    If you want to properly service your fridge its not to difficult to do

    No all the vent covers are off. The sweet spot on mine is 2 lights. Now I'm dressed, didn't want to frighten the locals I've taken the bottom vent off and definitely have a nice blue flame. I've had problems with the terminal block before so I've taken that off and sprayed with switch cleaner. Just a waiting game to see if the burner keeps running and the fridge gets cold again

    Not any more - at least not on a Thetford and probably not on Dometic now. The gas now has a thermostat.

    Well it seems the terminal block was the problem. Fridge & freezer both getting cold again. Must put cleaning this down as a routine maintenance job (y)

    We first noticed the fridge was not great while in Croatia.
    The rest of the family went off and I took it apart to see what was what
    Lovely blue flame and it all looked spotless.
    When we finally got home I ripped it down again and this time removed the burner out and cleaned it all up until it shone.
    Also used a proper 'jet pick' and cleaned the tiny hole in the restrictor valve that feeds the burner
    When I put it back together I immediately noticed the difference in the sound the burner was making..
    Much noisier !
    Fridge worked just fine after that.. I now strip and clean the thing at least once a year

    I never really noticed the drop in performance until it was quite bad.. It is a slow process I guess and just creeps up on you..

    why would you put the burner back and then clean the flue way so any carp falls on the freshly cleaned burner

    Makes no odds Pete.. They are basically all the same mate..
    I have sorted out identical issues in various fridges from both Dometic and Thetford

    @Jaws
    I've got the fridge out and the burner in my hand. Looking through it should it be completely clear on the centre hole?

    I can see a very fine mesh. (Burner jet 43 according to the parts list?)

    Thanks in advance

    I would say that is a good example of how NOT to service a fridge the bloke struck me as a cowboy.
