RE: Dometic Fridge (again)
The replacement model is a rm2351 or 2354.
Either the thermosat works or dont, you can take the tip of the thermostat and set it in a cup of ice water to se if it clicks if it does its ok.
Check the back of the selector switch knobs for being worn out/not turning the switch.
Yes the flame flucuates somewhat but not much.
If you hear a bubbling sound in the back when on flame the cooling unit is clogged/bad.
While running a seperate lp appliance the lp water colum to the fridge should be 8", if not its the lp regulator a lp drop test wil tell you that.
