OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model PG8MAA036070AAJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8MAA036070AAJA gas furnace and matched system components. The run capacitor stores and releases the electrical charge needed to keep the blower or condenser fan motor running at peak efficiency. When this capacitor degrades or fails, you'll typically notice the fan motor humming without spinning, sluggish motor start-up, or the system shutting down on thermal overload shortly after startup. Replacing it promptly prevents costlier motor or compressor damage.

  • Specs: 7.5 MFD (microfarad) | 370V rated (440V compatible) | Oval case | Factory-matched tolerance | OEM Part # P291-0753 (superseded by P291-0754) | Cross-references: HC91CA007, GE 27L566
  • OEM vs Generic: OEM capacitors are manufactured to exact Carrier factory tolerances (±3% MFD). Aftermarket generics can run ±10% MFD deviation, increasing motor winding stress and reducing service life — especially in high-cycle applications like furnace blower motors.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Verify MFD and voltage ratings on your unit's data plate before installation.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PG8MAA036070AAJA and related Carrier, Bryant, and Payne models requiring a 7.5 MFD 370V oval single run capacitor. Note: Carrier sources capacitors from approved manufacturers (e.g., Genteq/GE); labeling on the unit may reflect the capacitor manufacturer rather than Carrier. Always confirm the MFD and voltage rating on your existing capacitor before ordering. Our fitment team is available to verify compatibility before you buy — order today and ships same day!

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Single Run Capacitor 7.5 MFD 370V — PG8MAA036070AAJA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Single Run Capacitor 7.5 MFD 370V — PG8MAA036070AAJA. 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 OEM Carrier Single Run Capacitor 7.5 MFD 370V — PG8MAA036070AAJA?
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?
