OEM Carrier Single Run Capacitor 7.5 MFD 440V for Model UPFLOW125FAUHC12B

This OEM single run capacitor is the factory-specified replacement for the Carrier UPFLOW125FAUHC12B upflow gas furnace. The run capacitor stores and releases the electrical charge that keeps the blower motor running at proper speed and efficiency. When this component fails, the furnace blower motor may hum without spinning, run sluggishly, overheat, or the furnace may fail to deliver conditioned air entirely — even if the burner fires normally. OEM part number P291-0753 has been superseded by the updated P291-0754, which carries an upgraded 440V rating (fully backward-compatible with the original 370V application).

• Specs: 7.5 MFD (microfarad) | 440V rated (replaces original 370V P291-0753) | Oval case form factor | ±6% capacitance tolerance | UL approved | RoHS compliant | Rated for 60,000 service hours
• OEM vs Generic: This OEM Carrier capacitor is manufactured to exact factory tolerances, ensuring proper motor starting torque and sustained run performance. Generic off-brand capacitors often exceed ±10% MFD tolerance, causing blower motor stress, premature wear, and shortened furnace system life.
• Install difficulty: 2/5 — Discharge the capacitor before touching terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Always photograph existing wiring before disconnecting terminals. Match HERM and FAN terminal labels exactly.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier UPFLOW125FAUHC12B upflow gas furnace. OEM part number P291-0753 is discontinued; P291-0754 is the current factory-authorized direct replacement at an upgraded 440V rating. Verify your unit's data plate MFD rating before ordering.
