OEM Carrier Single Run Capacitor 3 MFD 250V for Model PG9MAA036040AAKA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG9MAA036040AAKA gas furnace. The run capacitor supplies the continuous phase-shifted current that keeps the indoor blower motor spinning at rated speed. When this capacitor weakens or fails, you'll typically notice the blower motor humming without starting, the furnace short-cycling due to overheating from restricted airflow, or the motor running sluggishly and drawing excessive current. Replacing a failed run capacitor promptly protects the blower motor from permanent winding damage.

  • Specs: 3 MFD (microfarad) | 250V rated | Rectangular case | ±5% factory tolerance | 50/60 Hz | CSA listed | OEM part numbers: HC91PD001 / P291-0503
  • OEM vs Generic: This is a genuine OEM-grade capacitor meeting Carrier's exact factory tolerance of ±5%. Aftermarket generics often carry ±10% tolerance, causing the blower motor to run off-spec, generating excess heat and shortening motor life.
  • Install difficulty: 2/5 — Always discharge the capacitor before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Photograph all wiring connections before disconnecting. Replace like-for-like on MFD rating and voltage.
  • Warranty: 1-year OEM manufacturer warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG9MAA036040AAKA gas furnace indoor blower motor circuit. Always verify the MFD rating and voltage on your unit's data plate before ordering to confirm fitment. Have a question? Our HVAC parts specialists verify compatibility before you buy — order now and ship today.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG9MAA036040AAKA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG9MAA036040AAKA. 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 PG9MAA036040AAKA?
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.
