OEM Carrier Single Run Capacitor P291-1503 for Model PG8JAA036045ACJA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier PG8JAA036045ACJA packaged gas/electric unit. The single run capacitor provides the continuous phase-shifted voltage needed to keep the blower or condenser fan motor running efficiently after startup. When this capacitor weakens or fails, you'll typically notice symptoms such as a humming motor that won't spin, intermittent shutdowns, sluggish motor starts, or the unit tripping on thermal overload due to motor strain.

• Specs: Single run capacitor | Factory-matched MFD rating | 370V/440V rated | Cylindrical case | OEM tolerance ±3% for precise motor protection
• OEM vs Generic: This is the genuine OEM Carrier part, built to exact factory specifications. Generic aftermarket capacitors frequently carry a wider ±10% MFD tolerance, which accelerates motor winding wear and can shorten the service life of your blower or fan motor significantly.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Recommended tools: 1/4" nut driver, needle-nose pliers, and a multimeter capable of MFD testing. Photograph all wiring connections before disconnecting to ensure correct reinstallation.
• Warranty: Backed by a 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before 3PM local time.

Compatibility: Designed for the Carrier PG8JAA036045ACJA packaged gas/electric unit. Always verify the MFD and voltage ratings printed on your existing capacitor's label or your unit's data plate before ordering to confirm fitment. Not sure? Our HVAC parts specialists are available to verify compatibility before you place your order — no guesswork required.
