OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8JAA036045AAJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8JAA036045AAJA gas furnace. The run capacitor maintains a continuous phase-shifted current to keep the blower motor running at full torque and efficiency. When it degrades or fails, you'll typically notice symptoms like a sluggish or humming blower motor that won't spin up, reduced airflow, or a furnace that shuts down shortly after startup due to thermal overload on the motor windings.

  • Specs: 10 MFD (microfarad) ±6% | 370V rated | Oval case | 50/60 Hz | Non-PCB castor oil dielectric | 10,000 AFC protected | Operating temp: -40°C to +70°C
  • OEM vs Generic: This is a genuine Carrier/Totaline OEM capacitor held to tight ±6% MFD tolerance. Off-brand generics commonly run ±10% or worse, causing motor overheating, premature bearing failure, and shortened motor life — costing far more in the long run.
  • Install difficulty: 1/5 — One of the easiest HVAC repairs available. Always discharge the capacitor before touching terminals (use an insulated 10kΩ resistor or capacitor discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers. Photograph existing wiring before disconnecting. Typical DIY time: under 15 minutes.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for use in the Carrier PG8JAA036045AAJA gas furnace blower motor circuit. Cross-references include part numbers HC90BB010, HC91DA010, and HC91CA010. Verify the MFD rating and voltage on your existing capacitor or motor data plate before ordering. Not sure it fits?

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8JAA036045AAJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8JAA036045AAJA. 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 PG8JAA036045AAJA?
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.
