OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model UPFLOW100HCU12A

This OEM single run capacitor is the factory-specified replacement for the Carrier UPFLOW100HCU12A upflow air handler. Originally supplied under part number P291-0753 (now superseded by P291-0754), this oval-style 7.5 MFD 370V capacitor is responsible for sustaining the blower motor's continuous operation once it has started. When it degrades or fails, symptoms include a blower motor that hums but won't spin, sluggish airflow, intermittent shutdowns, or a tripped thermal overload on the motor — all signs the capacitor can no longer hold its charge.

• Specs: 7.5 MFD (microfarad) | 370V rated (440V-rated successor P291-0754 is a direct upgrade) | Oval form factor | OEM-matched ±5% tolerance for precise motor performance
• OEM vs Generic: The OEM Carrier capacitor is manufactured to exact factory tolerances. Generic capacitors often drift outside rated MFD values within the first season, increasing motor heat and accelerating winding failure in your blower motor.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting the old unit.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier UPFLOW100HCU12A upflow air handler. Note: P291-0753 was discontinued in November 2020; the current OEM equivalent is P291-0754 (440V), which is a direct drop-in upgrade. Always verify the MFD rating on your unit's data plate before ordering. Need fitment confirmation?
