Central Air Conditioner Condenser fan motor does not run
When the condenser fan is not running, the outdoor unit may overheat and your central air conditioner can stop cooling. The most likely cause is a failed run capacitor, especially if the condenser fan motor is noisy, overheated, or the capacitor is bulging or leaking. Next, check the motor control board, which can prevent the motor from running at the proper speed or at all. If the board is working, the fan motor itself may have failed. A defective capacitor can also cause the AC fan motor not to run, while a failed condenser fan motor is a less common possibility. This condenser fan troubleshooting requires testing for incoming voltage with a multimeter, so shut off power at the disconnect box and circuit breaker before inspecting parts. Testing or replacing components inside the outdoor condensing unit involves 240V line voltage and should be handled by a qualified technician if you are not trained to work safely around it. Refrigerant work is not part of this repair, but any sealed-system service requires an EPA 608-certified technician. Enter your model number to find the exact run capacitor, motor control board, fan motor, or condenser fan motor for your central air conditioner.
01 - 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.

Common
02 - 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.
Common
03 - Central Air Conditioner Fan Motor
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.
Common
04 - Central Air Conditioner Motor
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.
Common
05 - Central Air Conditioner Capacitor
If the capacitor is defective, the fan motor might be noisy, overheat, or not run at all. To determine if the capacitor has failed, inspect the capacitor. If the capacitor is bulging or leaking, replace it.
Common
06 - Central Air Conditioner Condenser Fan Motor
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.
