OEM Carrier Single Run Capacitor P291-1503 for Model PG8MAA048070ACJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8MAA048070ACJA gas furnace. The single run capacitor maintains a continuous phase-shifted current to keep the blower motor running efficiently at full speed after startup. When this capacitor begins to fail, you'll typically notice symptoms such as the blower motor humming without spinning, sluggish or slow-starting blower operation, intermittent shutdowns due to overheating, or increased energy consumption as the motor struggles under electrical stress.

• Specs: OEM Part Number P291-1503 | Single Run Capacitor | Factory-matched MFD and voltage ratings | Engineered to Carrier's exact tolerance specifications for the PG8MAA048070ACJA platform
• OEM vs Generic: This is a genuine OEM Carrier capacitor, manufactured to precise ±5% or tighter MFD tolerance. Aftermarket alternatives often run ±10% or worse, causing accelerated motor winding wear, premature bearing failure, and shortened blower motor life — ultimately costing more in the long run.
• Install Difficulty: 2/5 — A straightforward swap for a qualified technician or experienced DIYer. Always discharge the capacitor fully before handling terminals. Recommended tools: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode), and insulated discharge resistor. Photograph all wiring connections before removal.
• Warranty: Backed by a 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier PG8MAA048070ACJA packaged gas furnace. Always verify the MFD rating and voltage printed on your existing capacitor's label or the unit's data plate before ordering. Not sure if this is the right part?
