Overview

This is a genuine OEM definite-purpose contactor for the ICP/Tempstar/Heil RGS210HDAA0AAAA furnace/condensing unit. The contactor is the electrically-operated switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. A 24-volt control signal pulls in the coil, closing the high-voltage line contacts. This listing covers OEM part 1171554 (2-pole, 30A, 24V coil) and the alternate 1172449 (3-pole, 40A, 24V coil). When a contactor fails, the most common symptoms are a unit that won't start, chattering or buzzing at the contactor, pitted or welded contacts that keep the compressor running, or visible arcing and burn marks on the terminals.
