This OEM 2-pole definite purpose contactor (part number 1178074) is the switching relay that energizes the compressor and condenser fan motor in your ICP/Tempstar/Heil RGS091LFCB0AAA system. Rated for 30 amps with a 24-volt control coil, the contactor closes when the thermostat calls for cooling and delivers line voltage to the outdoor unit. The contacts gradually pit, burn, and weld from the high inrush current of every compressor start. Typical failure symptoms include a unit that won't start, a humming or buzzing condenser, contacts welded closed so the compressor never cycles off, or a single click with no engagement. A worn contactor is one of the most frequent and affordable HVAC repairs.
