OEM Carrier Single Run Capacitor 10 MFD 370V for Model PY1PEA048100AGBA

This factory-spec single run capacitor (OEM part number P291-1003) is the direct replacement for the Carrier PY1PEA048100AGBA packaged unit. The run capacitor provides the sustained electrical charge needed to keep the blower or fan motor spinning at correct speed and efficiency. When the capacitor degrades or fails, symptoms typically include the motor humming but not starting, weak or reduced airflow, intermittent operation, or the unit tripping on thermal overload due to motor strain. Replacing this low-cost component promptly prevents cascading damage to the motor windings — a repair that costs many times more.

• Specs: 10 MFD (microfarad) | 370V rated (370/440V compatible) | Oval case form factor | ±5% factory tolerance | 50/60 Hz rated
• OEM vs Generic: OEM capacitors are built to Carrier's exact tolerance specifications, ensuring consistent motor performance and longevity. Generic aftermarket capacitors often carry a wider ±10% MFD tolerance that can accelerate motor wear and shorten equipment lifespan.
• Install difficulty: 1/5 — One of the easiest HVAC repairs. Tools needed: screwdriver, needle-nose pliers, multimeter (to verify discharge). Always discharge the capacitor fully before handling terminals, and photograph the existing wiring before disconnecting. No refrigerant certification required.
• Warranty: 1-year OEM warranty coverage. In-stock and ships same business day from our warehouse.
