OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8JAA042090AAJA

This OEM single run capacitor is the factory-specified replacement part (P291-1003) for the Carrier PG8JAA042090AAJA gas furnace. The run capacitor provides the sustained electrical charge needed to keep the blower motor running at the correct speed. When this capacitor fails, you may notice the blower motor humming but not spinning, weak or intermittent airflow, the furnace short-cycling, or a complete blower motor failure — leaving your system unable to distribute conditioned air through your home.

  • Specs: 10 MFD (microfarad) | 370V rated | Oval case | Factory-matched ±5% tolerance | 50/60Hz rated | Operating temp range: -40°C to +70°C
  • OEM vs Generic: This genuine Carrier Totaline capacitor is reliability-tested to 60,000 service hours using high-grade metallized polypropylene film. Generic capacitors often carry wider tolerance variances, which can accelerate blower motor wear and shorten system life.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter to verify capacitance. Photograph all wiring connections before disconnecting. Note: P291-1003 has been superseded by P291-1004 (440V-rated upgrade); a 440V capacitor is a safe, direct upgrade for a 370V application.
  • Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8JAA042090AAJA gas furnace. Always verify the MFD rating on your unit's data plate before ordering. Cross-references include: HC91CA010D, HC91CA010, HC90AB010, HC96AC010, and 97F9002. Have a fitment question?

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8JAA042090AAJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8JAA042090AAJA. 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 PG8JAA042090AAJA?
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?
