Overview

This is a genuine OEM 2-pole definite purpose contactor for the ICP/Tempstar/Heil RGS091HTAA0AAAA gas furnace and matched cooling system. The contactor is an electrically controlled switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. A 24-volt signal from the control circuit pulls in the coil, closing the line-voltage contacts and powering the outdoor unit. Available in 30-amp (OEM 1178074) and 40-amp (OEM 1178211) ratings, both with a 24V coil. Contactors wear out from pitted or welded contacts, a failed coil, or insect/debris intrusion that prevents the armature from seating — typical symptoms include a buzzing or chattering outdoor unit, a compressor that won't start, or a unit that runs nonstop and won't shut off.
