Overview

This OEM single-pole, 25-amp definite purpose contactor (ICP part number 1050699) is the electrical switch that powers the compressor and condenser fan on your ICP / Heil / Tempstar YG042GA2 unit. When the thermostat calls for cooling, the 24V coil pulls the contacts closed and sends line voltage to the compressor; when the call ends, the contacts open. Contactors are high-wear items — the contact points pit and burn over thousands of cycles, eventually welding shut or failing to close. A failed contactor is one of the most common no-cool service calls.
