Good morning, I have a problem with my oven and grill in my Motorhome, the oven is a Thetford make it lights but turns off after about 15-20minutes, you can relight it but it will not stay lit, same for the grill ..help
Is it the same on all burners? Make sure the thermocouple is in the flame. You may need new thermocouples. Generic ones can be bought on line cheaper than Thetford. Getting to them is the hard bit.
Rare for both thermocouples to fail. But the oven one is I agree the favourite. When it goes out and you relight what temperature setting is the oven on?
My grill fails every few years, always a blocked jet and pipe. Clean them out but do not poke anything through the jet orifice . There are specialist jet tools available but a good clean usually does the trick.
