Dometec caravan fridge problem

[TazzyRaithby]

Hi all.
I have a Swift Challenger SE580 2018 caravan.
We have always used the electric for the fridge. But recently my daughter and son in law used the van for our Grandsons moto x meetings. They have tried to put the fridge on gas, and the fridge was warm. I have investigated to see that the gas is on, the pilot light is on and the burner is hot, but still the fridge is warm. Yet it works on electric fine. Any ideas please.

Hi, and welcome Tazzy.

Hope someone can help, but initially it makes little sense. On electric, there is a heating element which generates the cooling. It is the same with the gas. And you say there is a flame.

Your picture shows set on Battery and the warning triangle as car is not connected with the engine running, Set it on Auto with the gas on and if not on mains it should light automatically on Gas.

Yes.
It works fine on electric. Gas is 100% going, I left it all night. But fridge warm.

Sorry, yes that was just to show what type of fridge we are dealing with.

Just to clarify there is no pilot flame when on gas on this range of Dometic fridges , the flame you see is the main flame , the fridge ignites the flame with a spark and detects the flame is running with an electrode which uses ' flame rectification'. The gas may be burning in the wrong place or have a partially blocked jet , so not enough heat is going up the chimney , or the chimney is blocked ( very unusual).To work on a gas appliance you need to be suitability qualified.

Hi
Thanks for the reply.
After a night , I took off the side panel on the caravan. The flame was on. The exhaust for the gas is running fine. But I check the fridge , it's warm.

You clearly needs some help to diagnose and repair the problem, Member's of the forum are at at a major disadvantage as we cannot see the details or prod things to work out what the problem is, It really needs a qualified fitter to to check the system out first hand. I suggest you contact your local Approved Workshop Scheme fitter and arrange to get together with them to sort it out.
