A run capacitor stores and releases an electrical charge to keep the blower motor running smoothly and efficiently. Rated at 5 MFD and 370 volts, it provides the continuous phase shift the PSC blower motor needs to start and maintain torque. When a capacitor weakens or fails, you'll typically see a blower that hums but won't spin, a motor that overheats and trips on thermal overload, intermittent airflow, or higher energy bills. Replacing a tired capacitor is one of the fastest, lowest-cost ways to restore proper furnace airflow.\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 Number\u003c\/td\u003e\n\u003ctd\u003e1170643\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eSingle Run, Oval\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\u003eCapacitance\u003c\/td\u003e\n\u003ctd\u003e5 MFD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e370V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eFurnace Blower Motor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eDirectly fits the ICP\/Heil\/Tempstar\/Comfortmaker WFMR070A036B1 furnace and many related WFMR-series air handlers and furnaces using the same blower motor.
