OEM Carrier Single Run Capacitor 10 MFD 370V for Model PF1MNA036000AAAA

This is the factory-specified OEM single run capacitor for the Carrier PF1MNA036000AAAA air handler. The run capacitor continuously supplies the phase-shifted electrical charge that keeps the blower motor spinning at rated torque and efficiency. When this capacitor degrades or fails, symptoms include the blower motor humming but not starting, sluggish airflow, motor overheating, or the unit tripping on thermal overload — all signs that the capacitor can no longer deliver its rated microfarad output.

• Specs: 10 MFD (microfarad) | 370V–440V rated | Oval case | ±5% tolerance | 50/60 Hz | 10,000 AFC protected | Non-PCB dielectric fluid | UL approved current interrupter
• OEM vs Generic: This factory-matched OEM capacitor (P291-1003) is built to Carrier's exact tolerance spec. Generic capacitors often run at ±10% MFD or higher, causing the blower motor to draw excess current, shortening both motor and capacitor life.
• Install difficulty: 2/5 — Always discharge the capacitor before handling — even a failed capacitor can hold a dangerous charge. Tools needed: flathead screwdriver, needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal. This is a straightforward swap accessible inside the air handler cabinet.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
