This OEM contactor set is the factory replacement for the switching contactors in ICP / Heil / Tempstar model RGS303HDEA0AAAA. It includes part 1171554 (2-pole, 30 amp, 24V coil) and part 1183142 (3-pole, 60 amp, 24V coil). A contactor is an electrically operated switch: when the 24V control circuit energizes the coil, the contacts close and pass line voltage to the compressor and condenser fan. Over time the contacts pit, arc, and weld, or the coil burns out — causing the equipment to hum without starting, run continuously, or fail to start at all. Installing the exact OEM contactor restores clean, reliable line-voltage switching at the rated amperage.
