OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8MAA024045AAJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8MAA024045AAJA gas furnace blower motor circuit. The run capacitor provides the sustained phase-shifted current that keeps the blower motor spinning at correct speed and torque. When it degrades or fails, you'll notice symptoms like a sluggish or humming blower motor that struggles to start, reduced airflow, motor overheating, or a furnace that trips on thermal overload shortly after ignition. Replacing this low-cost part promptly protects the far more expensive blower motor from burnout.

  • Specs: 10 MFD (microfarad) | 370V rated | Oval case form factor | ±6% tolerance | 50/60 Hz | Non-PCB dielectric fluid | 10,000 AFC protected | Operating temp: -40°C to +70°C
  • OEM vs Generic: This is a genuine Carrier/Totaline-sourced capacitor manufactured to exact factory specifications. Generic capacitors often carry wider MFD tolerances (±10% or more), which accelerates motor winding wear and shortens blower motor life — especially in a continuously running furnace application.
  • Install difficulty: 1/5 — One of the easiest HVAC repairs. Discharge the capacitor terminals before touching (use an insulated screwdriver across the terminals). Tools needed: flathead screwdriver, needle-nose pliers, multimeter (to verify old cap is bad). Always photograph the existing wiring before disconnecting. No refrigerant handling required.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PG8MAA024045AAJA gas furnace blower motor circuit. OEM part number P291-1003 (Totaline/Carrier); superseded by P291-1004 (440V-rated upgrade — a direct, compatible replacement). Always confirm the MFD rating on your existing capacitor's label before ordering. Have a question about fitment? Our HVAC parts specialists verify compatibility before you buy — contact us today and get your unit back up and running fast.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8MAA024045AAJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8MAA024045AAJA. 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 PG8MAA024045AAJA?
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.
