OEM Carrier Single Run Capacitor 15 MFD 370V for Model PF1MNB048000AAAA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier PF1MNB048000AAAA fan coil unit. The run capacitor maintains a continuous phase-shifted current to keep the blower or fan motor running efficiently after startup. When this capacitor fails, common symptoms include the motor humming but not spinning, the system short-cycling, or a complete motor no-start condition — all of which leave your system unable to move conditioned air through the space.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case form factor | 50/60 Hz rated | Non-PCB dielectric fluid | UL-approved current interrupter
• OEM vs Generic: This is a genuine OEM Carrier/Totaline capacitor held to exact factory MFD tolerance (±5%). Generic aftermarket units often run ±10% or worse, accelerating motor winding stress and shortening equipment life.
