Overview

This is an OEM 2-pole definite purpose contactor (Part Number 1171554) for the ICP / Tempstar / Heil RGS181LDBA0AGAA gas furnace and matched condensing unit. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor when the 24V control circuit calls for cooling. Rated at 30 amps per pole with a 24-volt coil, it handles the inrush and running current of the outdoor unit. When a contactor fails you'll see pitted or welded contacts, a chattering hum, or a unit that won't start even though the thermostat is calling — all signs the contacts can no longer make a clean connection.
