Dometic refrigerator keeps tripping the thermal limit switch

I have a 2003 dometic refrigerator, RM2652, with an updated panel (update done in 2009 as it had originally been recalled). I just bought the rv used a few weeks back and upon plugging it in to power the refrigerator, the thermal limit switch keeps tripping. I'm not using propane, but rather shore power. As a result, the refrigerator keeps shutting down.

I replaced the 5 amp and 3 amp fuses a few days ago on the replaced circuit board as they were no longer functional.

Anyone else run into this issue or know of a solution to resolve the issue?

    The pros will be here soon, but first, please clarify that you have a new "main board" (replaced by you?--why?) and now the new board has both the 5a (for 120v) and the 3a (for 12v) fuses blown.

    What is the sequence of events exactly? It matters for figuring this out.

    Have you had it working on propane (requires 12v to work the fridge controls)? Still works on propane now you replaced the 3a fuse?
