The run capacitor provides the sustained electrical charge that keeps the blower motor spinning at correct speed throughout every heating cycle. When the capacitor degrades or fails, common symptoms include a humming blower that won't spin up, sluggish airflow, the furnace overheating on high-limit lockout, or a motor that runs hot and shuts down prematurely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 10 MFD (microfarad) | 370V rated (370\/440V compatible) | Oval case | ±5% capacitance tolerance | 50\/60 Hz | Operating temp: -40°C to +70°C | Non-PCB dielectric | UL Listed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM Totaline\/Carrier capacitor is subjected to 100% electrical testing at the factory and features a patented pressure-sensitive interrupter for safe failure. Generic capacitors often carry wider MFD tolerances (±10%), which shortens blower motor life and can void motor warranties.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor fully before handling.
