A dual run capacitor delivers a phase-shifted voltage boost to both the compressor and the outdoor condenser fan motor, giving each motor the torque it needs to start and run efficiently. Rated at \u003cstrong\u003e35\/5 MFD, 370V\u003c\/strong\u003e, this part includes the OEM capacitor mounting plate (1183001) and oval retaining clamp (1171552) so it seats securely in the control box. A failed run capacitor is one of the most common causes of a condenser that hums but won't start, a fan that won't spin, or a unit that trips the breaker on startup.\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\u003eOEM Part Numbers\u003c\/td\u003e\n\u003ctd\u003e1183001 (Capacitor Plate), 1171552 (Clamp, Oval)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eDual Run Capacitor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP \/ Tempstar \/ Heil\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacitance\u003c\/td\u003e\n\u003ctd\u003e35\/5 MFD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage Rating\u003c\/td\u003e\n\u003ctd\u003e370V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShape\u003c\/td\u003e\n\u003ctd\u003eOval\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTolerance\u003c\/td\u003e\n\u003ctd\u003e±6%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eEngineered for the ICP-family RHS181H0CA0AAAA 1.5-ton heat pump and shared chassis units sold under the Tempstar, Heil, Comfortmaker, and Arcoaire brands.
