I had temperature cycling with my Norcold.
Drove me crazy for a couple of weeks until I read the manual and found out it was the "auto defrost" cycle.
The Auto defrost is just a 2 hour shutdown every 48 to 54 hours IF RUN CONTINOUSLY AND NEVER SHUT OFF. THAT will not cause any noticeable temp rise. UNLESS you happen to open the lower door numerous times when it is shut down for that 2 hours. To STOP that auto defrost, you just turn the refer ON and OFF once a day for 10 seconds. Then it will NEVER auto defrost. This is a Norcold only feature. It ONLY defrosts the Evap fins, nothing else. Doug
