The run capacitor maintains a continuous phase-shifted current to the blower motor's start winding, keeping it spinning efficiently throughout every heating and cooling cycle. When this capacitor weakens or fails, you'll notice symptoms like a sluggish or humming blower motor that won't start, intermittent airflow loss, blower motor overheating, or a furnace that locks out due to insufficient airflow across the heat exchanger.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 10 MFD (microfarad) | 370V rated (440V-rated successor P291-1004 is a direct drop-in) | Oval case | Factory ±5% capacitance 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 a genuine Carrier\/Totaline-sourced capacitor, reliability-tested to 60,000 service hours per UTC application parameters.
