OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8MAA066135ADJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8MAA066135ADJA gas furnace. The run capacitor provides the sustained phase-shifted current that keeps the blower motor spinning at proper speed and torque throughout each heating cycle. When it degrades or fails, you'll notice symptoms such as a humming blower that won't spin up, sluggish motor start, overheating, or the furnace shutting down on a limit fault shortly after ignition — all classic signs of capacitor failure in the blower circuit.

• Specs: 10 MFD (microfarad) | 370V rated (440V compatible) | Oval case | ±5% tolerance | 50/60 Hz | AFC protected | Non-PCB | Operating temp: -40°C to +70°C
• OEM vs Generic: This OEM Carrier/Totaline capacitor is manufactured to exact factory tolerance (±5%), ensuring correct motor current, extended blower life, and full warranty coverage. Generic aftermarket capacitors often deviate to ±10% MFD, increasing motor heat and accelerating winding failure.
• Install difficulty: 1/5 — One of the simplest HVAC repairs. Tools needed: flathead or Phillips screwdriver, needle-nose pliers, multimeter (to verify discharge). Always discharge the old capacitor before touching terminals, and photograph all wiring before disconnecting.
• Warranty: 1-year OEM factory warranty included. Ships same business day from our warehouse in original manufacturer packaging.

Compatibility: Direct OEM replacement for Carrier model PG8MAA066135ADJA gas furnaces. This part is also referenced as superseded by P291-1004 in some distributor systems — both are the same 10 MFD 370V oval single run specification. Confirm the MFD and voltage ratings on your existing capacitor's label before ordering. Our fitment team is available to verify compatibility before you buy — order today and get same-day shipping.
