OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8MAA036045ADJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8MAA036045ADJA gas furnace. The run capacitor provides the continuous phase-shifted current that keeps the blower motor spinning at rated speed and efficiency. When this capacitor degrades or fails, symptoms include a blower motor that hums but won't spin up, a furnace that overheats and trips the high-limit switch, or a motor that runs sluggishly and draws excessive current — all of which can lead to expensive motor burnout if left unaddressed.

• Specs: 10 MFD (microfarad) | 370V rated (370/440V compatible) | Oval case | ±5% factory tolerance | 50/60 Hz | -40°C to +70°C operating range | Non-PCB construction
• OEM vs Generic: This is a genuine Carrier/Totaline (Hartland Controls) OEM capacitor matched to exact factory tolerances. Generic capacitors often run ±10% MFD deviation, causing increased motor slip, reduced efficiency, and premature winding failure.
• Install difficulty: 1/5 — One of the easiest HVAC repairs. Tools needed: flat-head screwdriver, needle-nose pliers, and a multimeter to verify capacitance before installing. Always discharge the old capacitor by shorting its terminals through a 20kΩ resistor before handling. Photograph wiring orientation before disconnecting.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse in original factory packaging.

Compatibility: Fits Carrier model PG8MAA036045ADJA gas furnace. OEM part number P291-1003 (superseded to P291-1004 — functionally identical replacement). Verify the MFD rating and voltage on your motor's data plate before ordering. Our team is available to confirm fitment — order with confidence and get back up and running today.
