The run capacitor stores and releases the electrical charge required to keep the condenser fan motor running continuously throughout every cooling cycle. A failing run capacitor typically presents as a humming condenser with no fan movement, a fan that spins only when manually assisted, or intermittent short-cycling — all of which will quickly escalate to compressor damage if left unaddressed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 4 MFD (microfarad) | 370 VAC rated | Oval case form factor | 50\/60 Hz | Replaces OEM part numbers P291-0403 and P291-1503 (superseded)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory-authorized replacement, manufactured to exact ±5% MFD tolerance. Generic capacitors commonly run ±10% or worse, accelerating motor bearing wear and reducing compressor longevity over multiple seasons.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always disconnect power at the disconnect box and allow 5 minutes for the capacitor to self-discharge before touching any terminals.
