OEM Carrier Single Run Capacitor 10 MFD 370V — P291-1003 for Model PG8JAA048135ABJA

This is the factory-specified OEM single run capacitor for the Carrier PG8JAA048135ABJA gas furnace. Part number P291-1003 is an oval-case run capacitor rated at 10 MFD (microfarad) at 370V AC. The run capacitor keeps the blower motor spinning efficiently at full speed during each heating cycle. When this capacitor weakens or fails, you'll typically notice the blower motor humming without starting, running sluggishly, drawing excess current, or short-cycling — all signs the capacitor can no longer sustain the motor's operating charge.

• Specs: 10 MFD (µF) | 370V AC rated | Oval case form factor | ±5% tolerance | 50/60 Hz | Operating range -40°C to +70°C | Replaces HC91CA010D, HC91CA010, HC90AB010, HC96AC010, 97F9002
• OEM vs Generic: This is a genuine OEM-specified Carrier capacitor built to exact factory MFD tolerance. Aftermarket capacitors often carry ±10% variance, which accelerates motor winding wear and can shorten blower motor life — especially in a high-cycle furnace application like the PG8JAA series.
• Install difficulty: 1/5 — One of the easiest HVAC repairs. Power down and lock out the furnace at the breaker, discharge the capacitor terminals with an insulated resistor or screwdriver before touching, then swap the two-terminal connections. Tools needed: flathead screwdriver, needle-nose pliers, multimeter (to confirm discharge). Always photograph wiring before disconnecting.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8JAA048135ABJA gas furnace blower circuit. Cross-references: HC91CA010D, HC91CA010, HC90AB010, HC96AC010, 97F9002. Always verify the MFD rating and voltage on your unit's existing capacitor data label before ordering — never substitute a lower MFD or lower voltage rating. Have a fitment question?
