OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model UPFLOW100HCU%12

This OEM single run capacitor is the factory-specified replacement part P291-0753 for the Carrier UPFLOW100HCU%12 air handler and upflow system. The run capacitor stores and releases the precise electrical charge needed to keep the blower or fan motor running efficiently at full speed. When this capacitor weakens or fails, symptoms typically include a humming motor that won't spin, reduced airflow, intermittent shutdowns, or a system that trips on thermal overload shortly after starting — all signs pointing to a capacitor that can no longer hold its rated charge.

• Specs: 7.5 MFD (microfarad) | 370V rated (370/440V compatible) | Oval case | ±5% factory tolerance | Cross-references: HC91CA007, GE 27L566
• OEM vs Generic: This is the factory-matched OEM capacitor. Generic replacements often carry ±10% MFD tolerances, which places additional thermal stress on the motor windings and significantly shortens motor service life compared to the OEM-spec part.
• Install difficulty: 2/5 — Always discharge the capacitor fully before touching terminals — stored charge can cause serious injury. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting the old capacitor.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship the same business day from our stocked warehouse.

Compatibility: Designed for the Carrier UPFLOW100HCU%12 upflow air handler. Verify the MFD rating and voltage on your unit's data plate before ordering — using an incorrect MFD value will damage the motor. Note: OEM part P291-0753 may ship as successor part P291-0754 per Carrier's updated part supersession. Questions about fitment? Our HVAC parts specialists confirm compatibility before you order.
