Broan Central Air Conditioner Condenser fan motor does not run
Is your Broan central air conditioner condenser fan not running? The outdoor condenser fan may not be spinning even though the system calls for cooling. The most likely cause is a failed run capacitor, which can make the condenser fan motor noisy, cause it to overheat, or prevent it from starting. Next, check the motor control board, followed by the fan motor itself, the condenser motor, a separate capacitor, or the condenser fan motor. A bulging or leaking capacitor should be replaced, while a motor that receives the correct voltage but will not run may need replacement. These checks can help diagnose an AC fan motor not running, an AC condenser fan not working, or an outdoor AC fan not spinning. Turn off power at the disconnect box and circuit breaker before inspecting parts. Testing for 240V line voltage should be performed only by someone qualified to work safely around live electrical circuits; hire a licensed HVAC technician if you are unsure. This repair does not normally involve refrigerant handling, but any sealed-system work requires EPA 608 certification. Enter your Broan model number to find the exact replacement condenser fan motor, capacitor, or control board for your central air conditioner.
01 - Broan 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 - Broan 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.
