Q: What does the AC Control Relay do?

A: Relays and contactors are used in HVAC control circuits to turn things on and off such as blower motor, condenser fan motor or a compressor. Relays and contactors work in much the same way in a typical HVAC control circuit.

Q: What is a 12 volt automotive relay?

A: Most 12 volt relays operate accessories in a motor vehicle. Applying a small amount, as low as .2 amps of current to the relay coil closes contacts to feed power to an accessory that requires more current to operate, usually over 20 amps.

Q: What is an AC compressor relay?

A: The AC compressor relay is an integral part of the system. Without an operable relay, electricity cannot be sent to the compressor, and it will not function despite having a good belt, good clutch and other components.

Q: What is an AC relay switch?

A: A relay is an electromagnet with an internal spring-loaded lever to switch electrical contacts. To energize the relay, alternating current (AC) or direct current (DC) is passed through the coil of the electromagnet, magnetizing the core to attract the lever.
