OEM Carrier Single Run Capacitor P291-1003 for Model PG8MAA036045ABJA

This is the factory OEM single run capacitor for the Carrier PG8MAA036045ABJA gas furnace. The run capacitor provides the sustained phase-shifted current that keeps the blower motor spinning at proper speed and efficiency. When this capacitor fails, symptoms include a blower motor that hums but won't start, a motor that runs slowly or overheats, or a furnace that trips on high-limit lockout due to insufficient airflow. Replacing it with the correct OEM part (P291-1003) ensures the motor receives exactly the capacitance it was engineered for — protecting your investment and restoring full system performance.

• OEM Part Number: P291-1003 | Single run capacitor | Factory-specified MFD and voltage rating matched to the Carrier PG8MAA036045ABJA blower motor
• OEM vs Generic: OEM capacitors are manufactured to strict ±5% tolerance, matching the exact motor specs. Generic replacements often carry a ±10% tolerance, which can cause motor strain, premature bearing failure, and shortened compressor or blower life.
• Install Difficulty: 2/5 — Discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter for verification. Always photograph existing wiring before disconnecting the old capacitor.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed and tested for Carrier model PG8MAA036045ABJA. Always verify the MFD and voltage rating on your unit's data plate or existing capacitor before ordering to confirm fitment. Our parts specialists are available to verify compatibility before you buy — no guesswork required.
