The run capacitor provides the sustained phase-shifted current that keeps the blower motor spinning at proper speed and efficiency. When this capacitor weakens or fails, you'll typically notice a blower motor that hums but won't spin, a furnace that struggles to circulate air, or a system that overheats and trips on thermal limit — all classic signs of capacitor failure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 10 MFD (microfarad) | 370V rated | Oval case | ±5% factory tolerance | 50\/60 Hz | Operating temp: -40°C to +70°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the factory-matched OEM capacitor sourced through Carrier's Totaline\/Replacement Components Division.

Always verify the MFD rating and voltage printed on your existing capacitor's label before ordering to confirm fitment. Note: P291-1003 has been superseded by P291-1004 (440V-rated upgrade); both are functionally interchangeable on this model. Have questions about compatibility?
