OEM Carrier Single Run Capacitor 10 MFD 370V for Model PF1MNC030008AAAA

This OEM single run capacitor (Part# P291-1003) is the factory-specified replacement for the Carrier PF1MNC030008AAAA fan coil unit. The run capacitor maintains the continuous phase shift needed to keep the blower motor spinning at rated speed and efficiency. When this capacitor degrades or fails, you'll typically notice the blower motor humming without starting, running slowly, overheating, or shutting off entirely — leaving you with no airflow and potential motor damage if left unaddressed.

• Specs: 10 MFD (microfarad) | 370V rated | Oval case | ±6% tolerance | 50/60 Hz | Non-PCB dielectric fluid | 10,000 AFC protected
• OEM vs Generic: This is a genuine Carrier OEM capacitor manufactured to exact factory tolerances. Generic capacitors often deviate ±10% MFD or more, leading to accelerated motor wear, higher operating temperatures, and premature failure.
• Install difficulty: 2/5 — Always discharge the capacitor before handling any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting the old capacitor.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
