Intertherm Central Air Conditioner Condenser fan motor does not run
If your Intertherm central air conditioner has a condenser fan not running, the run capacitor is the most likely cause. A failed capacitor can make the fan motor noisy, cause it to overheat, or prevent it from starting; replace it if it is bulging or leaking. Next, check the motor control board, followed by the fan motor or condenser fan motor itself. If the motor receives the correct voltage but will not run and the capacitor is good, the motor is likely defective. A separate capacitor or less-common condenser fan motor may also be at fault. Turn off power at the disconnect box and circuit breaker before inspecting parts, and remember that testing incoming voltage involves dangerous 240V line voltage. If you are not qualified to work on energized HVAC equipment, have a licensed technician handle electrical diagnosis. This symptom usually does not require refrigerant handling, but any repair inside the sealed system requires an EPA 608-certified technician. Enter your Intertherm central air conditioner model number to find the exact replacement run capacitor, motor control board, fan motor, or condenser fan motor for your unit.

Common
02 - Intertherm 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 - Intertherm 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 - Intertherm 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.
