Dometic fridge won't run on gas

[IanB1485]

I disagree with the thermocouple itself being faulty , IMO it's the selector switch.
One trick to try without pulling the fridge out is to , whilst holding the gas valve in and the flame is lit to gently turn the selector switch slightly back away from 'gas' and back to gas , if the indicator twitches slightly or starts to move to the green section , then it's definitely grease on the contacts of the switch contacts.

Yes, thermocouple, I suggested that in #4

I would clarify that to say the thermocouple circuit, as often the thermocouple itself is fine, it the electrical contacts, either in the switch that Ian B has written about, or in the valve where the thermocouple's connector is supposed to screw in and seat and make contact.

With this being a possible fault on a gas appliance, get a real professional to service and repair the fridge before something goes wrong and it all ends up in disaster .

Again. Much of that suggested in #4.

I take on board what Ian suggested. But a weakness in the control circuits is indicated. I would always start with the cheapest, so Ian’s switch, then the thermocouple, then the valve.

The gas system is not touched unless it is the valve that is at fault.

Unfortunately under gas safety ( installation and use) regulations 1998 'work' on a gas appliance includes moving it or dismantling any part of ,so even if you don't touch the gas side it should only be undertaken by a qualified person. To illustrate this point I was , after servicing a caravan including a full gas integrity check and noted on it that one of the gas burners wouldn't stay lit , asked to repair it.On pulling the oven forward to get at the lid switches ( I have stand on which to rest the front of oven) and the side panel to get at the gas valve and thermocouple the inline gasoline union to oven developed a tiny leak as detected by as my gas sniffer and manometer. A person who has not attended an approved gas course, who might be a very competent engineer in other disciplines may not have the equipment to check that after the work is completed the gas system is completely leak free and safe to use. Only 3 weeks ago a Motorhome/campervan in Livingston suffered a gas explosion.After working or repairing the oven you should call out a gas engineer/mobile caravan engineer to just check it out, I call out a friendly gas safe engineer to check my work when having worked on my home condensing boiler.
