OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model PG8UAA036045ABJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8UAA036045ABJA gas furnace. The run capacitor maintains a continuous phase-shifted electrical charge to keep the blower motor running at peak efficiency. When this component degrades or fails, you'll typically experience symptoms such as a humming motor that won't spin up, intermittent blower operation, or a furnace that short-cycles due to overheating from restricted airflow. Replacing a failing run capacitor promptly protects the blower motor from premature burnout — a far costlier repair.

  • Specs: 7.5 MFD (microfarad) ±6% | 370 VAC rated | Oval case | Cross-references: HC91CA007, GE/Genteq 27L566, C307L | Successor part: P291-0754 (440V upgrade)
  • OEM vs Generic: OEM capacitors are manufactured to Carrier's exact tolerance specifications. Generic units commonly run ±10% MFD variance, which increases motor winding stress and shortens blower motor service life over time.
  • Install Difficulty: 2/5 — Always discharge the capacitor before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Photograph all wiring connections before disconnecting. Verify MFD and voltage ratings on your unit's data plate before installation.
  • Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8UAA036045ABJA gas furnace blower motor circuit. Note: P291-0753 has been superseded by P291-0754 (440V rated); the 440V unit is a fully compatible upgrade for the original 370V application. Carrier sources capacitors from third-party manufacturers — the label on the capacitor will reflect the OEM manufacturer (e.g., Genteq), not the Carrier brand name. Always confirm the MFD and voltage rating on your unit's data plate before ordering. Questions about fitment? Our HVAC parts specialists verify compatibility before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8UAA036045ABJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8UAA036045ABJA. 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 PG8UAA036045ABJA?
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.
