Kenmore Central Air Conditioner Condenser fan motor does not run
When your Kenmore central air conditioner's condenser fan motor does not run, the condenser fan may not be spinning even though the system has power. The most likely cause is a failed run capacitor, which can make the AC fan motor noisy, overheat, or stop completely. Next, check the motor control board, which regulates motor operation and speed. If the board is working, the fan motor or condenser fan motor itself may have failed. A separate capacitor can also cause the AC fan motor not running symptom. Inspect capacitors for bulging or leaking, and check the motor for proper incoming voltage with a multimeter. This condenser fan troubleshooting involves 240V line voltage, so turn off power at the disconnect box and circuit breaker before inspection; live-voltage testing or electrical repairs should be handled by a qualified HVAC technician. Do not open the sealed refrigerant system or handle refrigerant without EPA 608 certification. Enter your Kenmore model number to find the exact replacement run capacitor, motor control board, capacitor, or condenser fan motor for your specific central air conditioner.
01 - Kenmore Central Air Conditioner Run Capacitor
If the run 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 run capacitor is bulging or leaking, replace it.

02 - Kenmore Central Air Conditioner Motor Control Board
The motor control board helps to maintain the desired motor speed of the blower. When the motor control board fails, the blower motor may not run at the correct speed or it may not run at all.
To determine if the fan motor is working, use a multimeter to test the incoming voltage to the motor. If the 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 fan motor.
