Dometic dmr702 problem

I have a 2015 Rockwood 2703ws. I am having issues with my fridge a dometic dmr702. It has power I in it on and switch it to auto. It's fine for a minute then throws the code saying display is not communicating with power module. What does this mean? I have checked all fuses and looked at wiring connections. All seem fine. Will not work electric or propane. Any ideas?? First camper new member

There's fuses behind your fridge on the circuit board have you checked those?
Glass old school fuses

If display works for just a few seconds it's most likley not a fuse or power supply. If display board also has controls, it could be a bad connection in cabling between boards. Next either board could be bad not recognized during start up. If in a pinch you can always connect A/C direct to chimney with a switch for manual control, not for long however.

I have checked those fuses.. Both were fine. Fridge is in a slide out and I went outside and into the panel to access these fuses.

VinceU.. Not sure what the chimney is and how long would that work.. I agree it is a cable from one board to another.. Maybe a bad board now the pictures bein shown have a bigger gap between the 110v and the power module
