OEM Carrier Single Run Capacitor P291-1503 for Model PH2PPB048000AA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier PH2PPB048000AA heat pump system. A run capacitor provides the continuous phase-shifted current that keeps the compressor or fan motor spinning efficiently during operation. When it fails, you'll typically notice a humming unit that won't start, a compressor that trips on thermal overload, or a system that short-cycles within the first few minutes of operation — all classic signs of capacitor failure.

• Specs: Single run capacitor | Factory-matched MFD and voltage rating | Round or oval case per OEM specification | ±5% tolerance for reliable motor performance
• OEM vs Generic: This is a genuine OEM Carrier capacitor (P291-1503), manufactured to exact factory tolerances. Generic capacitors frequently fall outside ±10% MFD tolerance, which accelerates motor winding wear, increases amp draw, and can shorten compressor life significantly.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before removing any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring before disconnecting. The capacitor is typically located inside the access panel of the condenser or air handler unit.
• Warranty: 1-year OEM factory warranty against defects. Orders placed by 3 PM local time ship same business day from our warehouse.

Compatibility: Designed for the Carrier PH2PPB048000AA heat pump system. Always verify the MFD rating and voltage stamped on your existing capacitor against the data plate on your unit before ordering. If you have any questions about fitment, our HVAC parts specialists are available to confirm compatibility before you buy — ensuring the right part the first time.
