The contactor is the electrically controlled switch that closes the high-voltage line to the compressor and condenser fan motor whenever the 24V control circuit calls for cooling or heating. This unit is rated 30 amps with a 24-volt holding coil and includes a shunt for the auxiliary leg. When the contactor fails, the outdoor unit either won't start at all or won't shut off, because the contacts can weld closed from arcing or burn open from pitting. Buzzing, chattering, or visibly burnt\/pitted contacts are the classic signs of a failing contactor.\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\u003eOEM Part Number\u003c\/td\u003e\n\u003ctd\u003e1172472\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\u003eTempstar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePoles\u003c\/td\u003e\n\u003ctd\u003e1-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\u003eFeatures\u003c\/td\u003e\n\u003ctd\u003eIncludes shunt\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 for the Tempstar T4H424GKC200 heat pump.
