OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model UPFLOW125HCU12B

This is the factory-specified single run capacitor for the Carrier UPFLOW125HCU12B upflow gas furnace. Carrier OEM part number P291-0753 (superseded by P291-0754) is an oval-style 7.5 MFD 370V run capacitor that provides the sustained electrical charge needed to keep the blower motor running efficiently during every heating cycle. When this capacitor degrades or fails, you'll typically notice the blower motor humming without spinning, a furnace that starts then short-cycles, or a unit that trips on a high-limit fault due to reduced airflow caused by a struggling motor.

• Specs: 7.5 MFD (microfarad) | 370V rated (370/440V compatible) | Oval case form factor | Factory-matched ±6% tolerance | Supersedes P291-0753 → current OEM replacement P291-0754
• OEM vs Generic: OEM-spec capacitors are manufactured to Carrier's exact MFD tolerance, ensuring proper motor torque and longevity. Generic aftermarket units frequently drift outside ±10% MFD tolerance, which accelerates blower motor wear and can void equipment warranties.
• Install Difficulty: 2/5 — Always discharge the capacitor before touching terminals using an insulated screwdriver across the terminals. Tools needed: flathead and Phillips screwdriver, needle-nose pliers, multimeter (to verify discharge and confirm MFD rating). Always photograph existing wiring before disconnecting. The capacitor is located in the blower or control compartment of the furnace.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility Note: Designed for the Carrier UPFLOW125HCU12B upflow gas furnace. Always verify the MFD and voltage rating on your unit's existing capacitor or data plate before ordering — voltage rating must be equal to or greater than the original specification.
