OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8MAA066135ACJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8MAA066135ACJA gas furnace. The run capacitor provides a continuous phase-shifted current to the blower motor's auxiliary winding, keeping it spinning efficiently throughout every heating and cooling cycle. When the capacitor weakens or fails, common symptoms include a furnace blower motor that hums but won't start, runs slower than normal, draws excess current, or trips a thermal overload — ultimately leading to reduced airflow, comfort complaints, and potential motor burnout if left unaddressed.

  • Specs: 10 MFD (microfarad) | 370V rated (370/440V compatible) | Oval case | ±5% capacitance tolerance | 50/60 Hz | 10,000 AFC protected | Non-PCB dielectric fluid | RoHS Compliant
  • OEM vs Generic: This is a genuine Carrier Totaline-series capacitor manufactured to factory tolerance. Generic aftermarket capacitors often carry a ±10% MFD tolerance, which accelerates motor winding stress, shortens blower motor life, and may void your equipment warranty.
  • Install difficulty: 2/5 — Before touching any terminals, discharge the capacitor safely using a resistor or an insulated screwdriver. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter with capacitance function. Always photograph the existing wiring before disconnecting terminals. The oval case mounts via a standard snap-in or strap bracket inside the blower compartment.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8MAA066135ACJA gas furnace blower motor circuit. Note: P291-1003 has been superseded by P291-1004 (440V-rated upgrade); both MFD ratings are identical and the upgraded voltage rating is a direct, compatible replacement. Always verify the MFD value on your original capacitor's label before ordering. Have a question about fitment? Our HVAC parts specialists verify compatibility before you buy — order now and receive same-day shipping.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8MAA066135ACJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8MAA066135ACJA. 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 PG8MAA066135ACJA?
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.
