5 Signs That Indicate Your AC Fan Motor Is Bad

Check the Capacitor. The start capacitor is a cylindrical component and plays a vital role in starting up your AC. The capacitor supplies the electric charge, which starts the condenser fan motor. Without that boost of power, the fan motor is unable to start. That''s why when the capacitor stops working, so does the air conditioner.
