When the thermostat calls for cooling or heating, the 24V control circuit energizes the contactor coil, pulling the 2-pole, 30-amp contacts closed and sending line voltage to the outdoor unit. Rated at 30A per pole with a 24-volt coil, it is built to handle the inrush current of compressor start-up cycle after cycle. Over time the silver contacts pit, burn, and weld from arcing, while ants, dirt, and corrosion can lodge under the contacts. Common failure symptoms include a buzzing or chattering outdoor unit, a compressor that hums but won't start, a condenser fan that runs continuously, or an outdoor unit that is completely dead while the indoor blower still runs. Replacing this inexpensive part is one of the most common HVAC service repairs.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\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\u003ePrimary Part Number\u003c\/td\u003e\n\u003ctd\u003e1171554\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAlternate Part Number\u003c\/td\u003e\n\u003ctd\u003e1172449 (3-Pole 40A)\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)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePoles\u003c\/td\u003e\n\u003ctd\u003e2-Pole\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContact Rating\u003c\/td\u003e\n\u003ctd\u003e30 Amps\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\u003ctr\u003e\n\u003ctd\u003eFit\u003c\/td\u003e\n\u003ctd\u003eOEM Direct Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct OEM fit for the ICP \/ Heil \/ Tempstar \/ Comfortmaker RHS181H0AA0AAAA heat pump condensing unit. ICP shares contactor platforms across many RHS, NHP, and HSS series outdoor units, so this 2-pole 30A 24V contactor is also a frequent replacement across comparable single-stage condensers.
