HEATING / AIR CONDITIONING: AIR CONDITIONING SYSTEM: B1451: Compressor Solenoid Circuit
B1451 - Compressor Solenoid Circuit

DESCRIPTION

In this circuit, the compressor assembly with pulley receives a refrigerant compression demand signal from the air conditioning amplifier assembly.

Based on this signal, the compressor changes the amount of compressor output.
