OEM Carrier Single Run Capacitor P291-4003 for Model PG9YAB060100AAAA

This OEM single run capacitor is the factory-specified replacement part (P291-4003) for the Carrier PG9YAB060100AAAA 96% AFUE gas furnace. The run capacitor provides the sustained phase-shifted current that keeps the blower or inducer draft motor spinning at proper speed and efficiency. A failing capacitor typically presents as a humming motor that won't start, sluggish blower performance, intermittent furnace lockout, or a motor that overheats and trips its thermal overload — all of which result in loss of heat and potential secondary component damage if left unaddressed.

• Specs: OEM Part Number P291-4003 | Single run capacitor | Factory-matched MFD and voltage rating | Round case design fits factory mounting bracket
• OEM vs Generic: This is a genuine OEM Carrier capacitor built to exact factory MFD tolerance (±3%). Aftermarket alternatives commonly run ±10% tolerance, which shortens motor winding life and can void blower motor warranties.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (to verify discharge). Photograph all terminal connections before removal. This is a straightforward swap with basic HVAC service knowledge.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed for the Carrier PG9YAB060100AAAA 60,000 BTU 96% AFUE gas furnace. Always verify the MFD and voltage rating printed on your existing capacitor against the data plate before ordering to confirm fitment. Our parts specialists are available to verify compatibility before you purchase — no guesswork required.
