Dometic DM2852
I am running out of options trying to fix our Dometic 2852 fridge.
The problem is that it tries to run on propane when it is plugged in.
First I checked power all the way to the board, meter is reading 119v going into the lower control board.
Next I tested the element out, it tested 0v, so the board is not trying to run the element.
I removed the board and tested each circuit, every thing seems ok, there was continuity where I expected it to be.
I replaced the board with a brand new one from Dometic.
SAME - EXACT - PROBLEM
So I am starting to get stuck on troubleshooting.
I tested the element (even though it is getting no power) the result was 41 ohm, expected is 40 ohm, within range.
I am having a hard time accepting that I now have two faulty boards here, with the exact same problem, one is brand new (not saying it would be impossible)....
Does anyone know what to do next? I could take it into service, I just haven't been happy with the work at the RV dealer.
This doesn't make sense, AC + DC power into board, no AC power out.
EDIT: This is with the setting in AUTO, and AUTO is my only option to run on AC power.
Also, everything works perfectly on propane.
