Capacitor and Contactor: AC Parts You Should Know About
The capacitor and contactor work together in your air conditioner or heat pump to help power the fan and compressor. A telltale sign that one or both of these components has failed is when your air conditioning system''s fan runs normally, but the air is not heating or cooling. The most likely cause is either a failed capacitor or contactor.
