Gas operation on Dometic

[Gene Masse]

When I got my 98 Casita it came with a Dometic RM2202 3 way fridge. It was missing the gas control parts. I was able to get a used fridge with all the parts. I got the parts I needed installed. I can get it lit but when I let go of the button the flame goes out. I tried cleaning the Thermocoupler but still won't stay lit. I would appreciate any help from anyone with some experience. I have another thermocoupler to try but does anyone have any other ideas?

Gene when I light mine I need to hold the button in for a fairly long time before letting it go or it will go out.... seems it needs to warm up before it will stay on.

Also you may need to have your regulator checked out, as they get old they can loose psi which could be the problem.

Also if there are any tiny spiders or webs inside the pipes it will give you trouble.

Pretty sure you will mind a manual in the documents center here for it which should have some trouble shooting tips in it.

I'll second and emphasize Carol's advice. You need to hold the button in until it will stay lit. How long does that take? Well, lets see - its the 21st Century now, and ...

Actually, it often takes anywhere from 30 seconds to well over a minute after the flame starts before it will STAY lit after releasing the button, and each unit will have its own "personality" and will act just a wee bit differently. After a few times, you will get to know yours and you will know if it needs 30 seconds, one minute, a minute and a half or whatever

Well I did hold it for quite a while but will try holding it for at least 2 minutes to make sure. I think the time I held it in was adequate but you never know.

Gene, I bought a used Dometic 3-way, everything worked fine when bench tested. During the installation, I unknowningly crimped the thermocoupler. The flame never would stay lit either... eventually discovered the crimp and bought a new Dometic thermocoupler, all was well.
