The ICP OEM contactor (part #1178074) is a 2-pole, 30-amp magnetic switch with a 24V control coil used in the RGS102HRCA0AAA gas furnace/condensing unit family. The contactor is the electromechanical relay that energizes the compressor and condenser fan motor when the thermostat calls for cooling. When the 24V coil is energized, the two poles pull in and close the high-voltage line contacts. Over thousands of cycles the contacts pit, arc, and weld, or the coil burns open — causing a unit that hums but won't start, chatters, or refuses to shut off. Replacing a worn contactor restores clean, reliable switching and protects downstream components.
