OEM Carrier Single Run Capacitor P291-0753 for Model PO8LAA036105AAJA

This OEM single run capacitor (part number P291-0753) is the factory-specified replacement for the Carrier PO8LAA036105AAJA system. A single run capacitor provides the continuous phase-shifted current that keeps either the compressor or the fan motor running efficiently after start-up. When this component degrades or fails, the motor it supports loses torque, draws excess amperage, and will eventually overheat or fail to start entirely — symptoms include a loud hum with no motor movement, intermittent short-cycling, or a tripped breaker.

• Specs: Single run capacitor | Factory-matched MFD rating | 370V / 440V rated (verify data plate) | Round or oval case | OEM tolerance ±3% MFD for precision motor protection
• OEM vs Generic: This is a genuine OEM Carrier part (P291-0753), manufactured to exact factory specifications. Generic alternatives often carry ±10% MFD tolerance, which accelerates motor winding wear and reduces compressor service life over time.
• Install Difficulty: 2/5 — Always discharge the capacitor before handling — stored charge can cause serious injury even with power off. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting terminals.
• 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 as a direct OEM drop-in replacement for the Carrier PO8LAA036105AAJA. Always confirm the MFD and voltage rating on your unit's data plate matches the capacitor specification before installation. Not sure it fits?
