OEM Carrier Single Run Capacitor P291-1503 for Model PH1PEB042000AAAA

This is the OEM factory-specified single run capacitor for the Carrier PH1PEB042000AAAA packaged heat pump unit. The run capacitor provides the sustained phase-shifted electrical charge required to keep the compressor or fan motor running efficiently after startup. When this capacitor degrades or fails, common symptoms include a humming condenser with no motor movement, the system short-cycling shortly after startup, warm air from a unit that appears to be running, or complete failure of the compressor or fan motor to spin up.

• Specs: Single run capacitor | OEM Part Number P291-1503 | Factory-matched MFD and voltage rating | Round or oval case per OEM specification | ±5% tolerance as factory-rated
• OEM vs Generic: This is a genuine OEM Carrier replacement — not an aftermarket substitute. OEM capacitors are manufactured to exact factory MFD tolerance, ensuring proper motor protection and full rated lifespan. Generic capacitors often carry a ±10% MFD tolerance, which can accelerate motor winding wear and reduce compressor longevity.
• Install Difficulty: 2/5 — A single run capacitor is one of the more accessible HVAC repairs. Always shut off power at the disconnect and discharge the capacitor terminals before handling. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter to confirm discharge. Photograph all wiring connections before removal.
• Warranty: Backed by a 1-year OEM factory warranty. Orders ship the same business day from our stocked warehouse.
