OEM Carrier Single Run Capacitor 15 MFD 370V for Model PH1PPB036000AAAA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier PH1PPB036000AAAA heat pump unit. The run capacitor provides the sustained electrical charge needed to keep the condenser fan motor running smoothly during each cooling or heating cycle. A failing run capacitor typically causes the fan motor to hum without spinning, the system to trip on high-pressure lockout, or the unit to hard-start and short-cycle — symptoms that worsen rapidly in peak-season heat.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case | ±5% factory tolerance | Carrier/Totaline OEM part P291-1503
• OEM vs Generic: This is a genuine Carrier OEM capacitor built to exact factory tolerance. Generic aftermarket units often deviate ±10% MFD, placing undue stress on motor windings and shortening the service life of your condenser fan motor.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Recommended tools: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Total job time: approximately 20–30 minutes for a DIY technician.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed to fit Carrier model PH1PPB036000AAAA heat pump condensers. Always verify the MFD rating and voltage on your existing capacitor's label or the unit's data plate before ordering. Note: P291-1503 has been superseded by P291-1504 (440V-rated upgrade); both are compatible form-fit-function replacements for this model. Our parts specialists are available to confirm fitment before you order — no guesswork required.
