OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model PG8UAA036045AAJA

This is the OEM-spec single run capacitor for the Carrier PG8UAA036045AAJA gas furnace and associated blower/fan motor circuit. The run capacitor stores and releases an electrical charge that keeps the blower motor running at proper speed and efficiency. When this capacitor fails, you'll typically notice symptoms such as the blower motor humming without starting, intermittent blower operation, or the furnace cycling off prematurely due to overheating caused by reduced airflow. Replacing this part promptly prevents secondary motor damage and restores normal heating performance.

  • Specs: 7.5 MFD (microfarad) | 370V rated (440V-compatible replacements acceptable as an upgrade) | Oval case | Cross-references: HC91CA007, GE 27L566 | Supersedes to P291-0754
  • OEM vs Generic: OEM capacitors are manufactured to Carrier's exact tolerance specifications (±5% MFD). Generic alternatives often carry ±10% tolerances, which can accelerate motor winding wear and reduce equipment lifespan over time.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting the old capacitor.
  • Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse.

Compatibility: Designed for use in the Carrier PG8UAA036045AAJA furnace platform. Always verify the MFD and voltage rating on your unit's data plate or existing capacitor before ordering to ensure a correct match. Have a question about fitment? Our HVAC parts specialists confirm compatibility before you buy — order with confidence and get back up and running fast.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8UAA036045AAJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8UAA036045AAJA. 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 PG8UAA036045AAJA?
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.
