The run capacitor continuously supplies the phase-shifted electrical charge that keeps the blower motor spinning at rated torque and efficiency. When this capacitor degrades or fails, symptoms include the blower motor humming but not starting, sluggish airflow, motor overheating, or the unit tripping on thermal overload — all signs that the capacitor can no longer deliver its rated microfarad output.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 10 MFD (microfarad) | 370V–440V rated | Oval case | ±5% tolerance | 50\/60 Hz | 10,000 AFC protected | Non-PCB dielectric fluid | UL approved current interrupter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory-matched OEM capacitor (P291-1003) is built to Carrier's exact tolerance spec. Generic capacitors often run at ±10% MFD or higher, causing the blower motor to draw excess current, shortening both motor and capacitor life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor before handling — even a failed capacitor can hold a dangerous charge. Tools needed: flathead screwdriver, needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal.
