Your AC May Not Be Turning On Due To A Faulty Contactor In The Condenser
Your air conditioner has a part called a contactor that's responsible for turning the compressor on and off so your AC turns on and cools your home and then shuts down. The contactor is controlled by your thermostat, and if something goes wrong with the contactor, your AC won't operate properly. Your AC may not start, or it may not shut down. Here's how the contactor works and how an air conditioning repair technician may handle replacing or repairing it when the contactor malfunctions.
