OEM Carrier Single Run Capacitor 3 MFD 250V for Model PG9MAA036040AAKA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG9MAA036040AAKA gas furnace. The run capacitor supplies the continuous phase-shifted current that keeps the indoor blower motor spinning at rated speed. When this capacitor weakens or fails, you'll typically notice the blower motor humming without starting, the furnace short-cycling due to overheating from restricted airflow, or the motor running sluggishly and drawing excessive current. Replacing a failed run capacitor promptly protects the blower motor from permanent winding damage.

• Specs: 3 MFD (microfarad) | 250V rated | Rectangular case | ±5% factory tolerance | 50/60 Hz | CSA listed | OEM part numbers: HC91PD001 / P291-0503
• OEM vs Generic: This is a genuine OEM-grade capacitor meeting Carrier's exact factory tolerance of ±5%. Aftermarket generics often carry ±10% tolerance, causing the blower motor to run off-spec, generating excess heat and shortening motor life.
• 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. Replace like-for-like on MFD rating and voltage.
• Warranty: 1-year OEM manufacturer warranty against defects. In-stock and ships same business day from our warehouse.
