OEM Carrier Single Run Capacitor 10 MFD 370V — P291-1003 for Model PG8MAA066110ACJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8MAA066110ACJA gas furnace. The run capacitor provides the sustained electrical charge that keeps the blower motor running at proper speed throughout every heating cycle. When it begins to fail, you'll notice symptoms such as the blower motor humming without spinning, sluggish startup, reduced airflow, or the motor shutting down shortly after ignition — leaving your home without heat. Replacing a worn capacitor promptly prevents costly secondary damage to the blower motor itself.

  • Specs: 10 MFD (microfarad) | 370V rated | Oval case form factor | ±5% factory tolerance | 50/60 Hz | Rated -40°C to +70°C operating range
  • OEM vs Generic: This OEM unit is manufactured to exact Carrier factory tolerances. Aftermarket capacitors commonly run at ±10% MFD variance, which accelerates motor winding stress and shortens blower motor life — costing far more in the long run.
  • Install difficulty: 2/5 — Always discharge the capacitor before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. The blower compartment is accessible via the lower furnace door panel.
  • Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Directly fits Carrier model PG8MAA066110ACJA gas furnace. Cross-references include HC91CA010D, HC91CA010, HC90AB010, HC96AC010, and 97F9002. Note: P291-1003 has been superseded — our listing supplies the direct OEM replacement at the same 10 MFD / 370V specification. Always verify the MFD and voltage rating on your unit's data plate before ordering. Have questions about fitment? Our HVAC parts team confirms compatibility before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8MAA066110ACJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8MAA066110ACJA. 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 PG8MAA066110ACJA?
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.
