rm 3807 refer

I am sure there is a post somewhere on this silly frig problem, but I cannot find it. Anyone care id I start a new thread here?!
I have just replaced the cooling unit on our rm3807 Dometic frig. After putting it back in the cabinet it came out of, and hooking everything up, I couldn't get the igniter to work(on 12 volt) We have a polarity problem here at the ranch along with a host of electricity problems...so I have been trying to fire up on 12 volt. Nothing... I disassembled the burner, and rechecked all of the wiring...and burner hookups. Still nothing...no igniter I then changed to polarity in the barn so I could hook to 110 to see if it would run on electric... Lo and behold on 110 the igniter worked...and she fired up on LP. Then it quit. I can get it to run for short periods of time on LP...both on 12 volt and 110, but it will not run for more than five or six minutes at a time before defaulting. Any Ideas? Thanks.

Runningbare,
Did you replace the circuit board when you replaced the cooling unit???

I have heard of similar issues and a new circuit board seemed to alleviate the problem.

Since you are in Upper Sandusky, OH, you might be able to get some help / advice from P&S Trailer services.

Thanks,
The batteries are good...strong lights and all...I did not replace the circuit board. Julie and I are hoping to get to Fremont this weekend. I will try to talk to P&S Trailer techs while I am there. John
