I know most people don't want to hear this but I would look at installation instructions and double check the clearances to the back wall and make sure the roof vent has a sloping "chimney" to it.
Rarely, if ever do RV manufacuters follow all the guide lines, especially the chimney part. Not doing so can severly effect cooling of a perfectly good fridge.
Unfortunately the 1210 has limited cooling power to start with so these guidelines are even more important.
The sensor for the fans don't last long either. Mine lasted exactly one week on a brand new fridge. The replacement part has held up so far.
