This OEM 2-pole definite purpose contactor (OEM part 1178074) is the switching relay that energizes the compressor and condenser fan on your ICP/Tempstar/Heil RGS091STBA0AAAA system. When the thermostat calls for cooling, the 24V control signal pulls in the contactor coil, closing two sets of 30-amp line-voltage contacts to power the outdoor unit. Over time the contacts pit, arc, and weld from repeated switching, and the coil can burn out. Common failure symptoms include a unit that won't start, a chattering or humming contactor, contacts that stick closed (outdoor unit runs constantly), or visible burn/melt marks on the contactor body. Replacing a worn contactor restores clean, reliable switching and protects the compressor from voltage-starved hard starts.
