I have limited experience with refrigerators but have done some observation troubling shooting.
So, both freezer & refrig are not cooling, The compressor seems to be running, and the fan next to it is running as well.
The outside walls of the refrigerator, in the back and sides, seem cold when I touch it but insides both top & bottom units are room temperature. The fans inside both units appear to be running.
I don’t know what part is responsible for not cooling both freezer & refrigerator at the same time.
They were both working fine at night, and in the morning, the both were warm.
Any help would be appreciated,
