OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8MAA036045ADJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8MAA036045ADJA gas furnace. The run capacitor provides the continuous phase-shifted current that keeps the blower motor spinning at rated speed and efficiency. When this capacitor degrades or fails, symptoms include a blower motor that hums but won't spin up, a furnace that overheats and trips the high-limit switch, or a motor that runs sluggishly and draws excessive current — all of which can lead to expensive motor burnout if left unaddressed.

  • Specs: 10 MFD (microfarad) | 370V rated (370/440V compatible) | Oval case | ±5% factory tolerance | 50/60 Hz | -40°C to +70°C operating range | Non-PCB construction
  • OEM vs Generic: This is a genuine Carrier/Totaline (Hartland Controls) OEM capacitor matched to exact factory tolerances. Generic capacitors often run ±10% MFD deviation, causing increased motor slip, reduced efficiency, and premature winding failure.
  • Install difficulty: 1/5 — One of the easiest HVAC repairs. Tools needed: flat-head screwdriver, needle-nose pliers, and a multimeter to verify capacitance before installing. Always discharge the old capacitor by shorting its terminals through a 20kΩ resistor before handling. Photograph wiring orientation before disconnecting.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse in original factory packaging.

Compatibility: Fits Carrier model PG8MAA036045ADJA gas furnace. OEM part number P291-1003 (superseded to P291-1004 — functionally identical replacement). Verify the MFD rating and voltage on your motor's data plate before ordering. Our team is available to confirm fitment — order with confidence and get back up and running today.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8MAA036045ADJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8MAA036045ADJA. 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 PG8MAA036045ADJA?
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.
