OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8MAA066135AAJA

This OEM single run capacitor (Part# P291-1003) is the factory-specified replacement for the Carrier PG8MAA066135AAJA gas furnace. The run capacitor maintains the continuous phase-shifted current supply that keeps the blower motor spinning at rated RPM throughout the heating cycle. When this capacitor weakens or fails, you'll notice the blower motor humming without starting, running sluggishly at reduced airflow, or stalling mid-cycle — all signs that heat is not being properly distributed through your home.

  • Specs: 10 MFD (microfarad) | 370V rated (370–440V compatible) | Oval case | ±6% tolerance | 10,000 AFC protected | Non-PCB | Operating range: -40°C to +70°C | 50/60Hz
  • OEM vs Generic: This is the genuine Carrier/Totaline OEM capacitor manufactured to factory-exact tolerance. Generic aftermarket capacitors often exceed ±10% MFD variance, which accelerates blower motor winding stress and can dramatically shorten motor service life — especially on aging furnaces.
  • Install difficulty: 1/5 — One of the simplest HVAC repairs available. Discharge the capacitor before handling any terminals. Tools needed: flathead screwdriver, needle-nose pliers, multimeter. Always photograph wiring connections before disconnecting the old capacitor.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8MAA066135AAJA gas furnace blower motor circuit. Cross-references with Totaline P291-1003, Genteq C310L / 97F9002. Verify MFD rating and voltage on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8MAA066135AAJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8MAA066135AAJA. 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 PG8MAA066135AAJA?
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.
