OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY1PPB036060AAAA

This is the factory-authorized OEM single run capacitor for the Carrier PY1PPB036060AAAA. 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.

• Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case form factor | 50/60 Hz | Replaces OEM part numbers P291-0403 and P291-1503 (superseded)
• OEM vs Generic: 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.
• Install difficulty: 2/5 — Always disconnect power at the disconnect box and allow 5 minutes for the capacitor to self-discharge before touching any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance setting). Photograph all wire connections before removal.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM fit for Carrier model PY1PPB036060AAAA. Always verify the MFD and voltage rating on your unit's data plate before ordering — if your plate shows 370V you may substitute a 440V-rated capacitor, but MFD must match exactly.
