OEM Carrier Single Run Capacitor 10 MFD 370V — P291-1003 for Model PG8UAA048091ACJA

This OEM Carrier single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8UAA048091ACJA gas furnace. The run capacitor maintains a continuous phase-shifted current to keep the blower motor spinning at rated speed throughout every heating cycle. When it degrades or fails, the blower motor may hum without starting, run sluggishly, overheat, or stall entirely — reducing airflow, triggering limit switches, and ultimately causing furnace lockout. Replacing this low-cost component proactively is one of the most effective preventive maintenance steps you can take on any Carrier furnace.

  • Specs: 10 MFD (microfarad) ±6% | 370V rated | Oval case | 50/60 Hz | Non-PCB castor oil dielectric | UL-approved current interrupter | Multiple electrical terminals | –40°C to +70°C operating range
  • OEM vs Generic: This is the genuine Carrier-branded (Totaline) capacitor built to factory ±6% MFD tolerance. Off-brand generic capacitors often ship at ±10% or worse, causing the blower motor to run hotter and shortening its service life. OEM match means zero guesswork on fitment.
  • Install difficulty: 1/5 — One of the easiest furnace repairs available. Tools needed: flathead or Torx screwdriver (access panel), needle-nose pliers, multimeter (recommended to confirm capacitor failure before ordering). Always discharge the capacitor before handling and photograph wiring before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PG8UAA048091ACJA. Note: Carrier sources capacitors from third-party manufacturers — the label on the capacitor will reflect the component manufacturer's name (e.g., Totaline/Hartland Controls), not Carrier. This is normal and does not affect fitment or warranty. Verify the 10 MFD and 370V ratings on your unit's data plate before ordering. Have a fitment question? Our HVAC parts specialists verify compatibility before you buy — order with confidence.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8UAA048091ACJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8UAA048091ACJA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the capacitor on my Carrier PG8UAA048091ACJA?
Difficulty: Easy (20–30 min)
Step 1: Turn off power at breaker. Step 2: Open condensing unit panel. Step 3: Photograph the old capacitor wiring (Common/Herm/Fan). Step 4: Discharge old capacitor with insulated screwdriver. Step 5: Disconnect and remove old capacitor. Step 6: Mount new capacitor, reconnect wires to matching terminals. Step 7: Close panel, restore power, test. Tools: screwdriver, needle-nose pliers.
My AC hums but won’t start. What part do I need?
An AC that hums but won’t start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost to start the compressor. When it fails, you hear humming but the motor can’t overcome inertia. Other symptoms: fan spinning slowly, AC cycling on/off rapidly, or a visibly swollen capacitor. Fix: replace capacitor ($15–$80 DIY, 30 min).
Is this capacitor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier capacitor?
OEM strongly recommended. OEM capacitors have ±6% MFD tolerance vs aftermarket ±10%. The looser tolerance causes motor winding stress, higher temps, and shorter compressor life. Price difference is only $10–$20 — OEM is the clear value choice.
How fast does National HVAC Parts ship?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
