I first noticed this problem because the bread was completely thawed. I've been watching the freezer a few days and have noticed that the defrost warms the freezer to 70 F before the compressor turns on. I know because it switched from defrost to cooling in front of me. Otherwise I've noticed that the compressor will switch on at +2 F and the freezer temperature will get down to about -10 F.

Warm air blows from the vents in the back of the freezer during the defrost cycle.

The refrigerator temperature always stays between 40 F and 42 F..

Thanks in advance for your help.
