OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8MAA066110ADJA

This is the factory-specified OEM single run capacitor for the Carrier PG8MAA066110ADJA gas furnace. The run capacitor provides the sustained electrical charge required to keep the blower motor running at full efficiency once it has started. When this capacitor degrades or fails, you'll typically notice the blower motor humming without spinning, starting sluggishly, overheating and tripping the thermal limit, or the furnace short-cycling due to airflow faults — all classic signs of a weak or dead run capacitor.

  • Specs: 10 MFD (microfarad) | 370V rated (370/440V compatible) | Oval case | ±5% capacitance tolerance | 50/60 Hz | -40°C to +70°C operating range | Non-PCB dielectric fluid | UL Approved current interrupter
  • OEM vs Generic: This is a genuine Carrier/Totaline (Hartland Controls) OEM capacitor meeting exact factory tolerance specifications. Generic capacitors often deviate ±10% MFD, placing additional strain on blower motor windings and shortening motor life — especially in high-runtime furnace applications.
  • Install difficulty: 2/5 — Discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver or flat-blade screwdriver, needle-nose pliers, multimeter (to verify capacitance before install). Always photograph existing wiring before disconnecting terminals. Verify MFD and voltage ratings on the unit data plate before ordering.
  • Warranty & Shipping: 1-year OEM warranty. Ships same business day from our warehouse. Fast, trackable delivery nationwide.

Compatibility Note: Designed for the Carrier PG8MAA066110ADJA gas furnace. OEM part number P291-1003 (superseded by P291-1004). Cross-references include HC90BB010, HC91DA010, and HC90AB010 among others. Verify the 10 MFD and 370V ratings on your unit's capacitor label or data plate before ordering.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8MAA066110ADJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8MAA066110ADJA. 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 PG8MAA066110ADJA?
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.
