For the inquisitive look what’s inside a Dometic gas valve! (1 Viewer)

[Off da Grid]

Hi folks, I changed the gas valve on our Dometic fridge yesterday as it was sticking and not letting enough gas through.
It’s broke so might as well take it to pieces.
It has 2 sets of solenoids one at each end. I guess this is for safety in case one fails.

What really surprised me was the fact that the electrical connections are not shielded in any way.

Did you find out which one was sticking ?

Presumably the lack of oxygen means a spark couldn’t combust?

They'll be "intrinsically safe" so yes.

No I didn’t, annoyingly they both worked when I put power to them, but the fridge flame now roars as it should.
Could have been the off white filter was gumbed up in the feed pipe, can’t see it in the pics.
I wouldn’t want to take one of these valves apart and reuse it as the seals are very thin.

I am trying to fault find my fridge, what voltage did you use to test the valve?
I am assuming its 12 v. The supply i have to my valve is only 1.5v

BigSalmon , I think you will find that 1.5v would be the correct voltage at the gas valve (,from the power module) if your fridge is a RM7xxx series and possibly others.

1.5 is the correct voltage for those valves
