OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model PF1MNB030008AAAA

This OEM single run capacitor (part number P291-0753) is the factory-specified replacement for the Carrier PF1MNB030008AAAA. The run capacitor provides the continuous electrical phase shift needed to keep the fan or blower motor running smoothly and efficiently. When it degrades or fails, you'll typically notice symptoms such as a humming motor that won't start, a fan blade spinning sluggishly, intermittent shutdowns, or a complete no-start condition — all of which can quickly escalate to compressor or motor burnout if left unaddressed.

• Specs: 7.5 MFD (microfarad) | 370V rated (440V-compatible replacement accepted) | Oval case form factor | Factory-matched ±5% tolerance | Cross-references: HC91CA007, GE 27L566
• OEM vs Generic: This OEM-sourced capacitor meets Carrier's exact factory tolerance specifications. Generic aftermarket units commonly operate at looser tolerances, which can cause premature motor wear, increased energy draw, and shortened equipment life.
• Install difficulty: 1/5 — One of the simplest HVAC repairs. Always discharge the capacitor fully before touching terminals. Tools needed: flathead or nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Match MFD rating exactly; voltage rating must be equal to or greater than original.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PF1MNB030008AAAA. Always verify the MFD rating and voltage on your unit's data plate before ordering. Note that Carrier sources capacitors from third-party manufacturers — the label on the physical part will reflect the OEM supplier name, not Carrier. Questions about fitment?
