OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8JAA048110ADJA

This OEM single run capacitor (Carrier part number P291-1003) is the factory-specified replacement for the Carrier PG8JAA048110ADJA gas furnace. The run capacitor sustains the continuous phase-shifted current that keeps the blower motor spinning at proper speed and efficiency. When it degrades or fails, you'll typically notice a humming blower that won't start, sluggish motor spin-up, repeated tripping of the thermal overload, or a furnace that shuts down shortly after ignition due to airflow proving issues. Replacing a worn capacitor promptly protects the blower motor from overheating and premature failure.

• Specs: 10 MFD (microfarad) | 370V rated | Oval case | ±6% factory tolerance | 50/60 Hz | Non-PCB dielectric fluid | UL-recognized current interrupter | Operating range: -40°C to +70°C
• OEM vs Generic: This OEM Carrier/Totaline capacitor is manufactured to exact factory tolerances. Generic capacitors frequently run outside ±10% MFD tolerance, causing the blower motor to run hot, draw excess current, and fail prematurely — negating any cost savings.
• Install difficulty: 2/5 — Disconnect power and discharge the capacitor before touching terminals. Tools needed: 1/4" nut driver or flat-blade screwdriver, needle-nose pliers, multimeter (capacitance mode). Always photograph the original wiring before disconnecting terminals.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Direct OEM replacement for Carrier model PG8JAA048110ADJA gas furnaces. Note: P291-1003 has been superseded by P291-1004 — both part numbers are cross-compatible and represent the same 10 MFD 370V specification. Verify the MFD rating and voltage on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before you order — contact us anytime.
