What happens when an AC compressor is not engaged?
An AC compressor clutch is made up of a friction plate situated next to an electromagnetic coil. Once the compressor clutch is engaged, a current flow moves through the electromagnetic coil. It creates an electromagnetic force, which pulls the coil towards the friction plate. This gives power to the pump rotor that keeps the compressor running.
