The symptom: a 3A slow-blow fuse located by near the control circuit board (outside access door) would blow. Even with the unit switched off it would blow. When I would replace the fuse and switch on the Dom Battery switch....POOF!

The solution: Through the kindness of Nick Cagle, I used the control board he send me. I installed it and the I'm back up and running. I tested it on 12v and propane. Haven't checked it on AC yet which is next. I'm chilling some beer beverages now just to be sure it's going to stay running.

There must have been past issues with this circuit board since there was a Dinosaur Board in it. I'm going to send it in to get repaired. In the near future I plan on replacing the refrigerator with a unit that has a Danfoss compressor. These ammonia units don't seem to produce enough cool for the amount of power they use and the hassle of keeping them running.
