I have a Goodman AC that has been running fine. Still cools OK and the outside unit seems to run OK. Problem: When unit comes the fan blowere motor is cutting on and off. The outside unit continuties to run. When I change temp to lower the outside unit goes off and the fan continues to cut of and on for several minutes. Suggestions?

How fast is it cutting on and off ?

Cuts on and off every few seconds

You might try a new motor run capacitor. It is located close to the motor in the blower compartment. Get the same size and value. PS turn off the electric power before messing with it.

If this does not work then you might have to replace the entire motor and get a capacitor to match the requirements of the new motor.
