Our 1200LRIM was setting a No Co fault. We are pretty new to this motorhome and have only had it out once before. After a couple hard resets, it would continue to set the fault again after a few hours.
I replaced the board with a new Dynosour Board 621267-621271 and have the jumper in the 71 slot, but I still have the same problem.
(I took the number off of the old board, which is also a Dynaosour board and looks fairly new also)
I suspect that the previous owner used the wrong board.
I also swapped thermistors with a neighbor and the problem continued.
I hot wired the heating elements direct to 110v and the fridge will cool and work great, so I know the cooling unit is fine, but the computer is telling it to turn off the LP.
Any help is greatly appreciated.
Thank you very much,
Eric
