OEM Carrier Single Run Capacitor 10 MFD 370/440V for Model PG8MAA036110ABJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8MAA036110ABJA gas furnace. The run capacitor sustains a continuous phase-shifted current to keep the blower motor running at peak efficiency throughout each heating cycle. When the capacitor weakens or fails, common symptoms include the blower motor humming but not starting, sluggish motor spin-up, intermittent airflow, or the furnace shutting down on a thermal limit trip caused by reduced airflow. Replacing a weak capacitor early prevents costly blower motor burnout.

• Specs: 10 MFD (microfarad) | 370/440V rated | Oval case | ±5% tolerance | 50/60 Hz | 10,000 AFC protected | Non-PCB | OEM Part Number: P291-1003 (superseded by P291-1004)
• OEM vs Generic: This is a factory-authorized OEM capacitor manufactured to Carrier's exact ±5% MFD tolerance specification. Generic aftermarket capacitors often run ±10% or wider, which accelerates motor winding stress and shortens service life — especially critical for furnace blower applications that run continuously.
• Install difficulty: 2/5 — Always discharge the capacitor terminals before handling using an insulated resistor or discharge tool. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring connections before disconnecting. Total replacement time is typically under 15 minutes.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed for Carrier model PG8MAA036110ABJA gas furnaces. Also cross-references legacy part numbers HC91CA010D, HC91CA010, HC90AB010, and HC96AC010.
