Overview

This OEM contactor (part #1173690) is the 1-pole, 40 amp, 24V-coil relay that switches line power to the compressor and condenser fan in the ICP/Tempstar/Heil WPG4484115LKA1. When the thermostat calls for cooling, 24V energizes the coil and pulls the contacts closed, delivering 208/230V to the outdoor unit. Over time the contacts pit, burn, or weld, and the coil can open or stick, causing the compressor to run continuously, chatter, or fail to start. Typical failure signs include a buzzing or chattering contactor, pitted or melted contacts, and an outdoor unit that won't shut off or won't energize.
