The part(s) or condition(s) listed below for the symptom Heat pump fan motor does not run are ordered from most likely to least likely to occur. Check or test each item, starting with the items at the top of the page.
A run capacitor stores and releases a charge to start and run the condenser fan motor. If the capacitor is defective, the fan motor might be noisy, overheat, or not run at all. To determine if the run capacitor has failed, inspect the capacitor. If the dual run capacitor is bulging or leaking, replace it.

A dual run capacitor stores and releases a charge to start and run both the compressor and the condenser fan motor. If the capacitor is defective, the fan motor might be noisy, overheat, or not run at all. To determine if the dual run capacitor has failed, inspect the capacitor. If the dual run capacitor is bulging or leaking, replace it.
To determine if the condenser motor is working, use a multimeter to test the incoming voltage to the motor. If the condenser fan motor is receiving the correct voltage but the motor still won’t run, inspect the capacitor to ensure that it is not at fault. If the capacitor is not bulging or leaking, replace the condenser fan motor.
