Heil Central Air Conditioner Condenser fan motor does not run
If your Heil central air conditioner's condenser fan is not running, the outdoor AC fan may not be spinning even though the system has power. The most likely cause is a failed run capacitor, which can make the condenser fan motor noisy, overheat, or stop completely. A defective motor control board is another possibility, followed by a failed fan motor. If the motor receives the correct voltage but does not run, inspect the capacitor before replacing the motor. A separate capacitor or condenser fan motor can also fail, though these are less common causes. This condenser fan troubleshooting involves 240V line voltage, so turn off power at the disconnect box and circuit breaker before inspecting the condensing unit. Testing voltage with a multimeter or replacing electrical components should be handled by a qualified technician if you are not trained for live electrical work. The run capacitor, motor control board, fan motor, capacitor, and condenser fan motor are serviceable parts, but do not open the sealed refrigerant system. Enter your Heil central air conditioner model number to find the exact replacement part for your specific unit and verify fit before ordering.
01 - Heil 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 - Heil 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.
