The run capacitor provides the continuous phase-shifted current needed to keep the blower motor spinning at correct speed and torque. When this capacitor degrades or fails, you'll notice symptoms such as a humming blower motor that won't start, sluggish motor startup, overheating, or the furnace shutting down shortly after the blower engages. Replacing a worn capacitor promptly protects the motor from burnout — a far more costly repair.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | OEM part number P291-0503 | Factory-matched MFD and voltage rating | Round or oval case per OEM spec | ±5% tolerance for precise motor protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier capacitor built to exact factory tolerances. Aftermarket or generic capacitors often carry ±10% MFD variance, which can accelerate motor winding wear and void equipment warranties.
