OEM Carrier Single Run Capacitor P291-1503 for Model PH2PEB042000AA

This is the OEM factory-specified single run capacitor (part number P291-1503) for the Carrier PH2PEB042000AA heat pump or packaged unit. A run capacitor maintains a continuous phase-shifted current to keep the compressor or fan motor spinning at peak efficiency. When it degrades or fails, you'll notice symptoms like the unit humming but not starting, tripping the breaker, short-cycling, or drawing excessive amperage — all of which stress the motor and compressor far beyond normal limits.

• Specs: Single run capacitor | Factory-matched MFD rating | 370V or 440V rated (verify on unit data plate) | Round or oval case per original equipment | ±5% OEM tolerance for motor protection
• OEM vs Generic: The OEM P291-1503 is manufactured to Carrier's exact electrical specifications. Generic capacitors frequently ship with ±10–15% MFD variance, causing premature motor winding failure and voiding compressor warranties — the OEM part is always the safer long-term investment.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling (use a 20kΩ resistor or insulated discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring connections before disconnecting the old unit.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship the same business day from our stocked warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier PH2PEB042000AA. Always confirm the MFD rating and voltage stamped on your existing capacitor or the unit's data plate before ordering. Not sure it fits?
