The run capacitor maintains the continuous phase-shifted current required to keep the blower or condenser fan motor running efficiently after startup. A failing capacitor typically presents as a humming motor that won't spin, intermittent shutdowns, or a fan motor running slower than normal — all of which can quickly cascade into compressor or motor damage if left unaddressed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 15 MFD (microfarad) | 370V rated | Oval case form factor | ±5% factory tolerance | UL recognized | RoHS compliant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier\/Totaline OEM capacitor built to exact factory specifications. Generic capacitors frequently ship at ±10% MFD tolerance, leading to premature motor wear, increased amp draw, and shortened equipment life — the OEM part is the only safe choice for warranty-protected systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor fully before handling any terminals.
