OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model PH1PEB048000AAAA

This OEM single run capacitor is the factory-specified replacement for the Carrier PH1PEB048000AAAA packaged heat pump unit. Supplied under Carrier part numbers P291-0753 and P291-1503, the run capacitor provides the continuous electrical phase shift required to keep the condenser fan motor spinning efficiently after startup. When this capacitor weakens or fails, you'll typically notice the unit humming without the fan turning, the system short-cycling within minutes of startup, or a complete no-start condition — all signs of a capacitor that can no longer hold its rated charge.

• Specs: 7.5 MFD (microfarad) | 370V rated (440V-rated upgrades are backward-compatible per industry standard) | Oval case form factor | Factory-matched ±6% capacitance tolerance | 50/60 Hz compatible
• OEM vs Generic: OEM Carrier capacitors are reliability-tested to 60,000 service hours and use high-grade metallized polypropylene film dielectric. Generic capacitors often carry a wider ±10% MFD tolerance, which accelerates motor wear and reduces compressor lifespan over time.
• Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before opening the unit. Discharge the capacitor using a 10kΩ resistor before touching any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, insulated screwdrivers, multimeter. Photograph all wiring connections before disconnecting.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for Carrier model PH1PEB048000AAAA packaged heat pump units. OEM part numbers P291-0753 (original) and P291-1503 both apply to this platform — verify the MFD and voltage rating on your unit's capacitor data label before ordering. Note: P291-0753 has been superseded by P291-0754 (440V upgrade); both are functionally interchangeable on this model. Questions about fitment?
