The run capacitor remains energized throughout the entire operating cycle, continuously supplying the phase-shifted current that allows the fan motor or compressor motor to run efficiently. When this capacitor weakens or fails, you'll notice symptoms like a loud hum with no motor movement, a condenser fan that spins only when manually assisted, warm air output despite the compressor running, or the unit short-cycling under load. Replacing it promptly prevents accelerated motor wear and compressor damage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 4 MFD (microfarad) ± 5% | 370 VAC rated | Oval case form factor | 50\/60 Hz | Factory-matched Carrier OEM tolerance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This genuine Carrier \/ Totaline OEM capacitor is manufactured to exact MFD tolerance and subjected to 100% electrical testing before shipment. Generic aftermarket capacitors frequently ship at ±10% tolerance, which causes motors to draw excess current and shortens compressor life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off power at the disconnect and breaker. Allow 5 minutes for residual charge to dissipate before touching any terminals — capacitors store lethal voltage even after shutdown.
