OEM Carrier Single Run Capacitor 15 MFD 370V for Model PH1REA048000AAWA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier PH1REA048000AAWA packaged heat pump system. The run capacitor stores and releases the precise electrical charge needed to keep the fan motor or compressor running at peak efficiency. When it degrades or fails, you'll typically notice symptoms such as a humming unit that won't start, intermittent short-cycling, or a condenser fan that spins slowly or not at all. Replacing it promptly prevents cascading damage to the motor windings and compressor.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case | Single-element | 50/60 Hz | UL-approved current interrupter | Non-PCB dielectric fluid
• OEM vs Generic: This is a genuine OEM Carrier/Totaline capacitor engineered to exact factory tolerances (±5% MFD). Generic capacitors often carry ±10% tolerance, increasing motor stress and accelerating wear on the compressor and fan motor over time.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before removal. Average replacement time: 15–20 minutes.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
