Dometic RM2351 Control Board
I received my new control board (lower) for my Dometic R2351. Before I had nothing now it will work on propane but I get a check light when on AC.
I have done the following.
Checked all input voltages into the control board.OK
Checked signals from from the upper control board.OK
Checked thermistor resistance. 8K @ ~ 40 degrees
Checked heater resistance. 84.3 (175W element)
Checked fuses. (on control board)
Checked AC ripple on DC lines. Nominal 5VAC
Checked all grounds associated with the control board.
I did order two control boards. I have one waiting in the wings but am leery of putting another board in until I find root cause.
Ideas, suggestions or something I missed.
Cheers
Tim
