OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8JAA066135AAJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8JAA066135AAJA gas furnace, sold under Carrier part number P291-1003 (now superseded by P291-1004). The run capacitor provides the sustained electrical charge that keeps the blower motor spinning at correct speed throughout every heating cycle. When the capacitor degrades or fails, common symptoms include a humming blower that won't spin up, sluggish airflow, the furnace overheating on high-limit lockout, or a motor that runs hot and shuts down prematurely.

  • Specs: 10 MFD (microfarad) | 370V rated (370/440V compatible) | Oval case | ±5% capacitance tolerance | 50/60 Hz | Operating temp: -40°C to +70°C | Non-PCB dielectric | UL Listed
  • OEM vs Generic: This OEM Totaline/Carrier capacitor is subjected to 100% electrical testing at the factory and features a patented pressure-sensitive interrupter for safe failure. Generic capacitors often carry wider MFD tolerances (±10%), which shortens blower motor life and can void motor warranties.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Photograph or label all terminal wires before disconnecting. The blower motor terminal connects to the HERM or FAN lug; verify labeling on your motor.
  • Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Designed to fit Carrier model PG8JAA066135AAJA gas furnaces. OEM part number P291-1003 has been superseded by P291-1004 (370/440V, 10 MFD) — both are included in this listing. Always verify the MFD rating and voltage on your existing capacitor's label before ordering. Have a fitment question? Our HVAC parts specialists confirm compatibility before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8JAA066135AAJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8JAA066135AAJA. 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 PG8JAA066135AAJA?
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.
