OEM Carrier Single Run Capacitor 10 MFD 370/440V for Model PG8DAA060115ACJA

This OEM single run capacitor (part number P291-1003, superseded by P291-1004) is the factory-specified replacement for the Carrier PG8DAA060115ACJA gas furnace. The run capacitor provides the sustained phase-shifted current that keeps the blower motor spinning at full efficiency throughout every heating cycle. When this capacitor begins to fail, you may notice the blower motor struggling to reach full speed, running hot, humming without turning, or tripping the furnace's thermal overload — all classic signs of a degraded or open run capacitor that should be replaced immediately to avoid motor damage.

• Specs: 10 MFD (microfarad) | 370/440V rated | Oval case | ±5% tolerance | 50/60 Hz | Non-PCB dielectric fluid | Rated -40°C to +70°C operating range
• OEM vs Generic: This is a genuine Carrier Totaline-series capacitor, reliability-tested to 60,000 service hours per factory application parameters. Generic units often carry ±10% MFD tolerance and shorter rated service life, accelerating blower motor wear and potentially voiding equipment warranties.
• Install difficulty: 2/5 — Always shut off power at the breaker and discharge the capacitor before handling. Tools needed: 1/4" nut driver or flat-blade screwdriver, needle-nose pliers, multimeter (to verify capacitance before and after). Photograph all wire connections before disconnecting the old unit.
• Warranty: 1-year OEM factory warranty. UL approved, RoHS compliant, and 100% electrically tested at the factory. Ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PG8DAA060115ACJA gas furnaces. Note that P291-1003 has been superseded by P291-1004 (upgraded to 440V rating, fully backward compatible). Verify the 10 MFD rating and oval form factor on your unit's capacitor or data plate before ordering. Our fitment team is available to confirm compatibility before you buy.
