OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model UPFLOW100FAUHC12A

This OEM single run capacitor is the factory-specified replacement for the Carrier UPFLOW100FAUHC12A upflow gas furnace. The run capacitor stores and releases electrical energy to sustain steady blower motor operation throughout the heating or cooling cycle. When this capacitor weakens or fails, you'll typically notice the blower motor humming without spinning, the system short-cycling, or a complete loss of airflow — all symptoms that point directly to a failed run capacitor before any other component is blamed.

  • Specs: 7.5 MFD (microfarads) | 370V rated (440V-rated upgrade, P291-0754, also fits) | Oval case form factor | ±5% factory tolerance | Replaces discontinued OEM part # P291-0753
  • OEM vs Generic: OEM capacitors are manufactured to exact Carrier factory tolerances. Generic aftermarket units often drift outside ±10% MFD over time, placing added stress on the blower motor windings and accelerating premature motor failure.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Snap-in terminal connections make this a straightforward swap for most DIYers.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse — order by 3 PM local time for guaranteed same-day dispatch.

Compatibility: Designed for the Carrier UPFLOW100FAUHC12A upflow gas furnace. Note: OEM part number P291-0753 was discontinued in November 2020; P291-0754 (440V-rated) is the current authorized OEM replacement and is a direct, accepted upgrade for all 370V applications. Always verify the MFD rating on your unit's capacitor data label before ordering. Our parts specialists are available to confirm fitment — reach out before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier UPFLOW100FAUHC12A?
Yes. This is the factory-specified OEM capacitor for the Carrier UPFLOW100FAUHC12A. 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 UPFLOW100FAUHC12A?
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?
