OEM Carrier Single Run Capacitor P291-0753 for Model PG8DAA036050ACJA

This OEM single run capacitor (part number P291-0753) is the factory-specified replacement for the Carrier PG8DAA036050ACJA packaged gas/electric unit. A single run capacitor provides the continuous electrical charge needed to keep either the compressor or the fan motor running efficiently during each cooling or heating cycle. When this component fails, common symptoms include a loud humming or buzzing with no motor movement, intermittent short-cycling, or a complete failure of the condenser fan to spin — all of which can quickly cascade into compressor damage if left unaddressed.

• Specs: Single run capacitor | Factory-matched MFD rating | 370V/440V rated (verify against unit data plate) | Round or oval case per OEM specification | ±5% tolerance for precise motor performance
• OEM vs Generic: This is a genuine OEM Carrier part (P291-0753), manufactured to exact factory tolerances. Generic aftermarket capacitors frequently carry a ±10% MFD variance, which accelerates motor winding wear and shortens the operational life of your compressor or fan motor.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal to ensure correct reinstallation.
• Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.
