How to Replace a Central AC Capacitor or Contactor
The capacitor, sometimes called a "run capacitor," starts the condenser and the fan in the outdoor unit. If the capacitor fails, the air conditioner won''t run. What are the signs of a failed AC capacitor or contactor? The most common sign of a failed capacitor is a clicking sound followed by a buzz or hum.
