Overview

This genuine OEM 2-pole contactor (part #1178074) is the high-voltage switching relay for your ICP, Tempstar, and Heil RGS180SRAA0AAAA gas furnace and connected condensing unit. Rated at 30 amps with a 24-volt control coil, the contactor energizes when the thermostat calls for cooling or heating, closing its contacts to deliver line voltage to the compressor and condenser fan motor. Over years of cycling, the contact points pit, burn, and weld together from arcing, while the coil can lose its magnetic pull. A failed contactor is one of the most common no-cool/no-heat service calls — symptoms include a buzzing or chattering sound, a unit that won't start, or a condenser that runs continuously even after the thermostat is satisfied.
