Nordyne Central Air Conditioner Condenser fan motor does not run
When your Nordyne central air conditioner has a condenser fan not running, the outdoor fan may not spin, causing the system to overheat and stop cooling. The most likely cause is a failed run capacitor, which can make the fan motor noisy, hot, or unable to start. Next, check the motor control board, followed by the fan motor itself. If the motor receives the correct voltage but will not run, and the capacitor is not bulging or leaking, the fan motor may need replacement. A separate condenser motor, capacitor, or condenser fan motor can also fail and produce the same symptoms. This condenser fan troubleshooting involves testing electrical voltage with a multimeter, so turn off power at the disconnect box and circuit breaker before inspecting components. Testing or replacing parts in the outdoor condensing unit involves 240V line voltage and may be beyond a first-time DIY repair; use a qualified HVAC technician if you are not comfortable working safely around live electrical circuits. Refrigerant work is not part of this diagnosis, but any sealed-system repair requires EPA 608 certification.

01 - Nordyne 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 - Nordyne 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.
