OEM Carrier Single Run Capacitor 7.5 MFD 440V for Model UPFLOW120FAUHC12

This OEM single run capacitor is the factory-authorized replacement for the Carrier UPFLOW120FAUHC12 air handler and upflow furnace blower system. The run capacitor stores and releases the electrical charge that keeps the blower motor running at proper torque and speed throughout each heating or cooling cycle. When this component fails, you'll typically notice the blower motor humming without spinning, the system short-cycling, or the blower running sluggishly — all signs of a capacitor that can no longer hold its charge. Note: OEM part number P291-0753 has been superseded by the direct manufacturer replacement P291-0754, which features an upgraded 440V rating (up from 370V) for improved durability and longevity.

• Specs: 7.5 MFD (microfarad) | 440V rated (upgrade over original 370V) | Oval form factor | ±5% capacitance tolerance | UL approved pressure-sensitive current interrupter | RoHS compliant | Rated for 60,000 service hours
• OEM vs Generic: This is a genuine Carrier factory-authorized capacitor built to exact United Technologies reliability specifications, including high-grade metallized polypropylene film dielectric. Generic capacitors often use inferior dielectric materials and wider tolerance bands (±10%), which accelerates blower motor wear and reduces system efficiency over time.
• Install difficulty: 2/5 — Always discharge the capacitor before handling — even a failed capacitor can retain a dangerous charge. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to confirm capacitance before and after). Photograph all wiring connections before disconnecting. This is a single-terminal capacitor — straightforward swap with no wiring complexity.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Direct OEM replacement for Carrier model UPFLOW120FAUHC12 air handler / upflow blower systems. Supersedes discontinued part P291-0753 — P291-0754 is the current OEM-authorized equivalent. Verify the MFD rating and voltage on your unit's data plate or capacitor label before ordering.
