Update: I have gotten this unit to cool quite well 2x -5 in the freezer and lower 30's in the box. Buttt, then it stops working on electric and wants to switch to propane which I haven't reconnected yet. I just replaced the fuse to be sure about that and it still won't run on electric. I have triple checked the wiring and think I have the 12v relay and board correct now but if not would that cause this problem? BTW, it also has new heating elements and I put in a snip-the-tip thermister. What am I missing? If I miswired the relay or the 12v side of the board would that cause it? Any help would be greatly appreciated as we are supposed to leave for a month next Friday.
BTW it is a RM1350SM, manual door locks/latches.
Thanks
