Refrigerator-Grand tour

The lower freezer freezes but the upper refrigerator is not cooling. Is there a separate fuse or breaker?

Generally a single power feed and fuse for both upper and lower units.

Common problems can be bad thermostat, bad crimp on wires, bad ventilation. It is difficult to diagnose anything until the unit is removed.

Do you hear the compressor running?

I have the same refrigerator in my 2018. That was the first year for this model.

The upper and lower sections each have their own compressor and control logic. A common problem is a poor crimp or a loose connection to the terminal block on the upper section. A flickering light when the refrigerator is vibrated is one indication.

Sadly, the entire refrigerator must be pulled out to access the connections and it is big and heavy.
