OEM Carrier Single Run Capacitor 15 MFD 370V for Model PH1PPA036000AABA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier PH1PPA036000AABA heat pump / packaged unit. The run capacitor stores and releases the electrical charge needed to keep the fan motor spinning at consistent speed throughout the entire operating cycle. When it degrades or fails, you'll typically notice the unit humming without starting, the motor spinning slowly, the system short-cycling, or a complete no-start condition — all classic signs of capacitor failure.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case | 50/60 Hz | Factory-matched ±5% tolerance | Non-PCB dielectric fluid | UL-approved current interrupter
• OEM vs Generic: This is a genuine OEM Carrier/Totaline capacitor — factory-specified for the PH1PPA036000AABA. OEM units meet exact tolerance ratings. Generic alternatives often run ±10% MFD deviation, which accelerates motor winding wear and reduces compressor service life.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify capacitance). Photograph all wiring connections before disconnecting. This is a single-motor capacitor — confirm it serves the fan motor or compressor on your specific unit.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH1PPA036000AABA packaged heat pump unit. Always verify the MFD rating and voltage on your unit's data plate before ordering — never substitute a capacitor with a lower voltage rating. Our fitment team is available to confirm compatibility before you buy. Order now and ship today!
