OEM Carrier Single Run Capacitor P291-1003 for Model PG8MAA048110AAJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8MAA048110AAJA gas furnace. The run capacitor maintains a continuous phase-shifted current to keep the blower motor running at peak efficiency. When a run capacitor fails, the blower motor may hum without spinning, draw excess current, overheat, or cause the furnace to short-cycle — leaving you without heat or proper airflow. Replacing the capacitor promptly protects the blower motor from costly burnout.

  • Specs: OEM Single Run Capacitor | Factory-matched MFD rating | 370V / 440V compatible | Round capacitor case | ±5% tolerance per OEM specification
  • OEM vs Generic: This is a genuine OEM Carrier part — factory-matched to exact MFD and voltage tolerances required by the PG8MAA048110AAJA. Aftermarket capacitors often run ±10% MFD variance, accelerating motor wear and voiding manufacturer warranties.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter. Photograph all wiring before disconnecting leads. Average install time: 20–30 minutes.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PG8MAA048110AAJA gas furnace. Always verify the MFD and voltage ratings on your unit's data plate or existing capacitor before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before you buy — contact us today and we'll ship it out the same day.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8MAA048110AAJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8MAA048110AAJA. 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 PG8MAA048110AAJA?
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.
