OEM Carrier Single Run Capacitor P291-1003 for Model PG8MAA036045ACJA

This is the factory OEM single run capacitor (part number P291-1003) for the Carrier PG8MAA036045ACJA gas furnace. The run capacitor maintains a continuous phase-shifted current to the blower motor, keeping it spinning at rated torque and efficiency throughout every heating cycle. When this capacitor degrades or fails, you'll notice symptoms such as the blower motor humming without starting, sluggish or slow motor spin-up, overheating of the motor winding, or the furnace shutting down on a high-limit lockout due to insufficient airflow.

• Specs: Single run capacitor | Factory-rated MFD and voltage per Carrier specification for PG8MAA036045ACJA | Round or oval case (factory form-fit) | ±5% tolerance as required by OEM standard
• OEM vs Generic: This is a genuine OEM Carrier part. Generic capacitors frequently carry ±10% MFD tolerances, which accelerates motor bearing wear and reduces blower motor lifespan. OEM ensures exact electrical compatibility and preserves your equipment warranty.
• Install Difficulty: 2/5 — Discharge the capacitor fully before handling any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (capacitance mode). Always photograph existing wiring before disconnecting terminals.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships the same business day from our warehouse.

Compatibility: Designed specifically for the Carrier PG8MAA036045ACJA packaged gas furnace.
