Hi @John Balliet ,
What is the model number of the refrigerator?
Can you hear if the evaporator fan is operating?
It is located in the freezer compartment behind a panel.
If you open the door the fan should stop. When the door is closed the fan should start again. You may have to place your ear next to the fridge cabinet to hear it running and stopping etc. It will only run if the compressor motor is also running.
Do not confuse this fan with the condenser fan which is outside the compartments near the compressor. It can run whether the doors are open or not
