The run capacitor sustains a continuous phase-shifted current to keep the blower motor running at peak efficiency throughout each heating cycle. When the capacitor weakens or fails, common symptoms include the blower motor humming but not starting, sluggish motor spin-up, intermittent airflow, or the furnace shutting down on a thermal limit trip caused by reduced airflow. Replacing a weak capacitor early prevents costly blower motor burnout.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 10 MFD (microfarad) | 370\/440V rated | Oval case | ±5% tolerance | 50\/60 Hz | 10,000 AFC protected | Non-PCB | OEM Part Number: P291-1003 (superseded by P291-1004)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a factory-authorized OEM capacitor manufactured to Carrier's exact ±5% MFD tolerance specification. Generic aftermarket capacitors often run ±10% or wider, which accelerates motor winding stress and shortens service life — especially critical for furnace blower applications that run continuously.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor terminals before handling using an insulated resistor or discharge tool.
