Tempstar Central Air Conditioner Condenser fan motor does not run
When your Tempstar central air conditioner's condenser fan is not running, the outdoor unit may stop cooling and the compressor can overheat. The most likely cause is a failed run capacitor, especially if it is bulging or leaking. A defective motor control board is another possibility, followed by a failed fan motor, motor, or capacitor. If the capacitor looks normal, the condenser fan motor itself may be worn out. These faults can cause the condenser fan not spinning, the AC fan motor not running, or the AC condenser fan not working at all. Safe troubleshooting starts with a visual inspection after shutting off power, but testing incoming voltage or replacing parts inside the outdoor unit involves 240V line voltage and should be handled by a qualified HVAC technician if you are not trained to work safely around it. The motor control board may also affect blower operation, so confirm which motor has stopped before ordering a part. Enter your Tempstar model number to find the exact replacement run capacitor, capacitor, motor control board, fan motor, or condenser fan motor for your specific central air conditioner.

03 - Tempstar 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.
