If you suspect the condenser fan motor is bad you should check to be sure before you replace it. Begin your diagnosis by shutting the power off to the air conditioner.

Common Motor Problems

Next, you should check to see if the fan blade spins freely. If it does not, the motor should be replaced. If the blade spins freely, you should feel the motor to see if it is hot.

If the motor is hot, you should check it's run capacitor using our handy guide and replace it as necessary. If the run capacitor was bad, you should allow the fan motor to cool. Then you can turn the unit back on and see if the motor starts and comes up to speed. If the fan fails to start or does not run at full speed, it should be replaced.
