We have a Norcold DC451 in our 240. It appears to by cycling on and off at what I would consider, quick intervals.
It cools great, no issues there... But, it may run for 2 minutes, and then shut off for 3-4 minutes, and then may start up for another 1-2 minutes. It will do this pretty much on any temperature setting (once it gets up to temp that is). It will do it either on AC or on DC.
It does hold a consistent temperature, and doesn't seem affected by the frequent starts/stops (unlike a home fridge).
I fully cleaned/defrosted the unit, and it still does it. The temperature sensor is screwed into the bottom of the freezer tray (where the coils are running through), and when I remove it from it's holder and let it dangle in the ambient air, it will not cycle on and off (it just runs... for awhile I assume, but I got tired of waiting for it to shut off). It doesn't seem to drain the battery fast running this way either. I can go on the water for 8-9 hours and have the fridge on DC and it doesn't drain the selected (I have dual) battery much (I can still start the engine from it).
The fridge may have done this all along, but we have only spent the night on the boat three times this year, so I only notice it then.
Is this cycling normal?
