Overview

This is a genuine OEM 2-pole definite purpose contactor (OEM part #1178074) for the ICP/Tempstar/Heil RGS091LDAB0AAAA system. Rated at 30 amps per pole with a 24-volt control coil, the contactor is the electrically operated switch that delivers line voltage to the compressor and condenser fan motor on a cooling call. When the thermostat energizes the 24V coil, the contacts close and start the outdoor unit. Pitted, welded, or burned contacts are a leading cause of an outdoor unit that hums without starting, fails to shut off, or cycles erratically. Replacing this low-cost part restores dependable cooling and helps protect the compressor from damaging electrical faults.
