Air Conditioner Compressor Start Relay

Without this relay the ac compressor will not have power and the ac system will not function.

Air conditioner compressor start relay.

The capacitor provides the power needed to start and run the compressor the blower motor and the outer fan. The ac compressor relay is no different then other electrical relays its electrical contacts will eventually wear or burn out and the relay must be replaced. The ac compressor relay is responsible for supplying power to the ac compressor and clutch. The relay contains a low voltage coil and a high voltage switch sometimes called contact points when the thermostat switches on a low voltage signal energizes the appropriate relay.

The ac contactor relay and start run capacitor s see illustration below fail most often and are inexpensive. If the compressor isn t running but the fans work the start relay or compressor might have failed. Airtex 1r1056 air conditioner compressor control relay. 4 5 out of 5 stars 74.
