This OEM 2-pole definite purpose contactor (part numbers 1178074 and 1178211) is the electrical switch that energizes the compressor and condenser fan on your ICP / Tempstar / Heil RGS091HFBA0AAAA system. When the thermostat sends 24 volts to the coil, the magnetic core closes the contacts and delivers line voltage to the load. Rated at 30 amps (1178074) and 40 amps (1178211) across 2 poles with a 24V coil, it absorbs compressor inrush current without the contacts welding shut. A failing contactor reveals itself as a unit that hums but won't start, pitted or burned contacts, a buzzing or chattering coil, or no response when the system calls for cooling.
