Part 1171554 is a 2-pole 30-amp contactor and part 1183142 is a 3-pole 60-amp contactor, both with a 24V control coil. A contactor is the heavy-duty switch that closes the line-voltage circuit to the compressor and condenser fan when the 24V thermostat signal energizes the coil. Over time the contacts pit, weld, or burn, and the coil can fail open — leading to a system that won't start, chatters, or won't shut off. Installing the correct OEM contactor restores clean, reliable switching at the rated amperage.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Numbers\u003c\/td\u003e\n\u003ctd\u003e1171554 (2P), 1183142 (3P)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eDefinite Purpose Contactor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP \/ Heil \/ Tempstar \/ Comfortmaker\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePoles \/ Rating\u003c\/td\u003e\n\u003ctd\u003e2-Pole 30A \/ 3-Pole 60A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoil Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eDirect-fit OEM replacements for the ICP-family RGS303HEFA0AAAA and related Heil, Tempstar, and Comfortmaker units.
