OEM Carrier Single Run Capacitor 5 MFD 370/440V for Model PG9MAB036060AASA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG9MAB036060AASA gas furnace indoor blower motor circuit. The run capacitor provides the continuous phase-shifted current the blower motor needs to maintain steady rotation during every heating and cooling cycle. When this capacitor weakens or fails, the blower motor may struggle to start, run at reduced speed, draw excess amperage, or shut down on thermal overload — leaving you with a furnace that fires but delivers little or no airflow. OEM part number P291-0503 (current shipping equivalent: P291-0504) is the exact factory-matched replacement sourced by Carrier for this application.

• Specs: 5 MFD (microfarad) | 370/440V rated | Oval case | CBB65-V rated | ±6% factory tolerance | 50/60 Hz
• OEM vs Generic: OEM capacitors are manufactured to Carrier's exact tolerance spec, protecting blower motor windings from voltage stress. Generic units often run wider tolerances, increasing heat buildup and motor wear over time.
• Install difficulty: 1/5 — One of the easiest HVAC repairs. Power down the furnace at the breaker and disconnect switch before touching any terminals. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers, and a multimeter to verify discharge. Always photograph existing wiring before disconnecting leads.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse in original manufacturer packaging.

Compatibility: Directly fits Carrier model PG9MAB036060AASA gas furnace blower motor circuit. Always verify the MFD rating and voltage on your existing capacitor's label or your unit's data plate before ordering. Cross-references: P291-0503, P291-0504, 97F5705, 1178116.
