Dometic Fridge/freezer not lighting on gas.

[EuropeanWanderer]

I have problems with my Dometic not lighting on gas.
The igniter is firing but eventually times out. There is plenty of gas in the bottle. Both my Truma Combi6 and the stove light ok.

I recently had to remove the freezer to get to some heating ducts underneath it and when I disconnected the gas pipe I noticed some kind of white substance in the pipe that goes into the gas valve.

I don’t know if it’s a build up of some kind of chemical reaction, or if it’s supposed to be some kind of filter in the pipe.

Can anyone shed any light in this?

Have you tried to light your burner with a hand held gas lighter just to see if you have gas coming through

Depending on model Some Dometic parts diagrams show a filter (which can sometimes block) in the end of the gas supply pipe and that may be what you are seeing , the gas supply valve solenoid on some models can also stick and you may find it will free off and work if you give it a tap with a screwdriver or similar
