OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model UPFLOW120HCU12A

This OEM single run capacitor is the factory-specified replacement for the Carrier UPFLOW120HCU12A upflow gas furnace. The run capacitor stores and releases an electrical charge that keeps the blower motor spinning at the correct speed and torque throughout the heating cycle. When this component fails, you'll typically notice the blower motor humming without starting, the furnace short-cycling, or in some cases a complete loss of airflow — leaving the heat exchanger to overheat and trigger a high-limit lockout. OEM part number P291-0753 has been superseded by P291-0754, the current factory-authorized replacement at the same 7.5 MFD / 370V specification.

• Specs: 7.5 MFD (microfarad) ±6% | 370V rated (440V successor upgrade) | Oval case | UL approved | RoHS compliant | 60,000 service hour rated construction
• OEM vs Generic: This is a genuine Carrier-authorized capacitor manufactured to factory tolerance. Generic aftermarket capacitors commonly run outside ±6% MFD tolerance, which accelerates bearing wear and shortens blower motor life — leading to a repeat repair bill.
• Install difficulty: 2/5 — Always discharge the capacitor before handling by shorting the terminals with an insulated screwdriver. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Photograph all wiring connections before disconnecting. Replace one wire at a time to avoid miswiring.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier UPFLOW120HCU12A upflow gas furnace. Verify the MFD rating and voltage on your existing capacitor's label before ordering — specs must match or voltage may be equal/higher. Questions about fitment?
