OEM Carrier Single Run Capacitor P291-1003 for Model PG8MAA036045ACJA

This is the factory OEM single run capacitor (part number P291-1003) for the Carrier PG8MAA036045ACJA gas furnace. The run capacitor maintains a continuous phase-shifted current to the blower motor, keeping it spinning at rated torque and efficiency throughout every heating cycle. When this capacitor degrades or fails, you'll notice symptoms such as the blower motor humming without starting, sluggish or slow motor spin-up, overheating of the motor winding, or the furnace shutting down on a high-limit lockout due to insufficient airflow.

  • Specs: Single run capacitor | Factory-rated MFD and voltage per Carrier specification for PG8MAA036045ACJA | Round or oval case (factory form-fit) | ±5% tolerance as required by OEM standard
  • OEM vs Generic: This is a genuine OEM Carrier part. Generic capacitors frequently carry ±10% MFD tolerances, which accelerates motor bearing wear and reduces blower motor lifespan. OEM ensures exact electrical compatibility and preserves your equipment warranty.
  • Install Difficulty: 2/5 — Discharge the capacitor fully before handling any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (capacitance mode). Always photograph existing wiring before disconnecting terminals.
  • Warranty: 1-year OEM manufacturer warranty. In-stock and ships the same business day from our warehouse.

Compatibility: Designed specifically for the Carrier PG8MAA036045ACJA packaged gas furnace. Always verify the MFD and voltage rating on your existing capacitor's label or your unit's data plate before ordering to confirm fitment. Have a question about compatibility? Our HVAC parts specialists verify fitment before you buy — contact us before placing your order.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8MAA036045ACJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8MAA036045ACJA. 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 PG8MAA036045ACJA?
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?
