OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8JAA066135AAJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8JAA066135AAJA gas furnace, sold under Carrier part number P291-1003 (now superseded by P291-1004). The run capacitor provides the sustained electrical charge that keeps the blower motor spinning at correct speed throughout every heating cycle. When the capacitor degrades or fails, common symptoms include a humming blower that won't spin up, sluggish airflow, the furnace overheating on high-limit lockout, or a motor that runs hot and shuts down prematurely.

• Specs: 10 MFD (microfarad) | 370V rated (370/440V compatible) | Oval case | ±5% capacitance tolerance | 50/60 Hz | Operating temp: -40°C to +70°C | Non-PCB dielectric | UL Listed
• OEM vs Generic: This OEM Totaline/Carrier capacitor is subjected to 100% electrical testing at the factory and features a patented pressure-sensitive interrupter for safe failure. Generic capacitors often carry wider MFD tolerances (±10%), which shortens blower motor life and can void motor warranties.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Photograph or label all terminal wires before disconnecting. The blower motor terminal connects to the HERM or FAN lug; verify labeling on your motor.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Designed to fit Carrier model PG8JAA066135AAJA gas furnaces. OEM part number P291-1003 has been superseded by P291-1004 (370/440V, 10 MFD) — both are included in this listing. Always verify the MFD rating and voltage on your existing capacitor's label before ordering. Have a fitment question? Our HVAC parts specialists confirm compatibility before you buy.
