Possible Causes

Failed condenser fan motor, Faulty condenser temperature sensor, Control board fan driver failure

Safety first: Unplug the refrigerator before working at the rear compartment.

Inspect condenser fan: Remove rear access panel, check for free blade movement and obstructions.
Test fan motor: Measure resistance across motor leads; open circuit indicates failure. Replace if defective.
Check sensor (if equipped): Some models have a condenser temperature sensor; test resistance and replace if out of spec.
Control board check: If fan and sensor test good but do not receive power, the control board may be faulty and require replacement.
