OEM Carrier Single Run Capacitor 10 MFD 370V for Model PF1MNA030000AAAA

This OEM single run capacitor is the factory-specified replacement for the Carrier PF1MNA030000AAAA air handler. The run capacitor maintains a continuous phase-shifted current to keep the blower motor spinning at the correct speed and efficiency. When this capacitor weakens or fails, you'll notice reduced airflow, a humming blower motor that struggles to start, or a complete indoor blower failure — leaving your system circulating no conditioned air through the home.

• Specs: 10 MFD (microfarad) | 370V rated | Oval case form factor | Factory-matched ±5% tolerance | OEM Part Number: P291-1003
• OEM vs Generic: OEM capacitors are manufactured to Carrier's exact electrical specification. Generic off-brand capacitors commonly ship with ±10% or wider MFD tolerance, causing blower motor overheating, premature bearing wear, and shortened motor life.
• Install difficulty: 1/5 — One of the easiest HVAC repairs. Always disconnect power at the breaker and discharge the capacitor terminals before handling. Tools needed: flathead screwdriver, needle-nose pliers, multimeter. Photograph existing wiring before removing leads.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships the same business day from our warehouse.

Compatibility: Fits Carrier model PF1MNA030000AAAA air handler. Note: Carrier sources its capacitors from third-party manufacturers — the brand name printed on the capacitor body will reflect the capacitor manufacturer, not Carrier. Always verify the MFD and voltage rating on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy.
