I was hoping someone more knowable than myself like Chris Bryant would post by now, but from what I understand when the refer is run off level heat rises quickly the Norcold fix shuts it off at 700 degrees to prevent fires. The ARP system shuts it of around 350 to prevent the ammonia solution from hardening inside the tubes blocking the flow of ammonia. Someone posted awhile back doing some tests with various out of level conditions and how high the temps reached. A simple solution to this problem would be to put a temp sensor right above the heating element and adjust the levelers until the lowest temps are recorded, then set bubble gauge to be level.
