3 way frige

[HeloEngineer]

Good evening all!

I'm a little stuck with my fridge and would relish some input.

Bought camper a month ago. I've been fixing things bit by bit when I have enough time.

Todays task was the fridge!

It works on 12v and 240v however nothing happens on gas.
I've had it out of the unit and I'm getting 12v to the reigniter but nothing beyond it. (should I?)
Could the reigniter be unserviceable?
Can you buy them? PN- 407/1/72669/010

I believe the fridge is model RM211E.

Other than that I'm a bit stumped as I would have thought I'd hear the odd click.

As I said any advice would be most welcomed.

Cheers...
