OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model PG8UAA036045ABJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8UAA036045ABJA gas furnace. The run capacitor maintains a continuous phase-shifted electrical charge to keep the blower motor running at peak efficiency. When this component degrades or fails, you'll typically experience symptoms such as a humming motor that won't spin up, intermittent blower operation, or a furnace that short-cycles due to overheating from restricted airflow. Replacing a failing run capacitor promptly protects the blower motor from premature burnout — a far costlier repair.

• Specs: 7.5 MFD (microfarad) ±6% | 370 VAC rated | Oval case | Cross-references: HC91CA007, GE/Genteq 27L566, C307L | Successor part: P291-0754 (440V upgrade)
• OEM vs Generic: OEM capacitors are manufactured to Carrier's exact tolerance specifications. Generic units commonly run ±10% MFD variance, which increases motor winding stress and shortens blower motor service life over time.
• Install Difficulty: 2/5 — Always discharge the capacitor before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Photograph all wiring connections before disconnecting. Verify MFD and voltage ratings on your unit's data plate before installation.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8UAA036045ABJA gas furnace blower motor circuit. Note: P291-0753 has been superseded by P291-0754 (440V rated); the 440V unit is a fully compatible upgrade for the original 370V application. Carrier sources capacitors from third-party manufacturers — the label on the capacitor will reflect the OEM manufacturer (e.g., Genteq), not the Carrier brand name. Always confirm the MFD and voltage rating on your unit's data plate before ordering. Questions about fitment? Our HVAC parts specialists verify compatibility before you buy.
