When starting this refrigerator for the very first time, the cool-
ing cycle may require up to four hours of running time before
the cooling unit is fully operational.
Any time the vehicle is parked for several hours with the refrig-
erator operating, the vehicle should be leveled to prevent this
loss of cooling.
Also look of the evaporator fins inside the fridge. there should be a temp probe clipped to one of them. Is it clipped on the fin? Slide the temp probe higher up on the fin. This will net colder temps...
