OEM Carrier Single Run Capacitor P291-1003 for Model PG8UAA060155AAJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8UAA060155AAJA gas furnace. The single run capacitor continuously supplies the phase-shifted electrical current the blower motor needs to maintain torque during normal operation. When this capacitor degrades or fails, you'll typically notice the blower motor humming without spinning, the furnace shutting down on a thermal overload, or the unit short-cycling due to motor stress — all signs pointing directly to a failed run capacitor.

• Specs: Single run capacitor | Factory-matched MFD and voltage rating | Round case design | Meets OEM ±3% tolerance specification for the PG8UAA060155AAJA blower motor circuit
• OEM vs Generic: This is a genuine OEM Carrier part, built to exact factory tolerances. Generic or aftermarket capacitors often carry a wider ±10% MFD tolerance, which increases motor winding heat, accelerates bearing wear, and can shorten blower motor service life considerably.
• Install Difficulty: 2/5 — A straightforward swap accessible in the blower compartment. Always discharge the capacitor fully before handling terminals. Recommended tools: 1/4" nut driver, needle-nose pliers, insulated discharge resistor or screwdriver, and a multimeter to verify capacitance before and after installation. Photograph all wire connections before disconnecting.
• Warranty: Backed by a 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Engineered and factory-matched for the Carrier PG8UAA060155AAJA packaged gas furnace unit. Always confirm the MFD and voltage rating on your existing capacitor or equipment data plate before ordering to ensure a precise match.
