OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model UPFLOW100FAUHC12

This OEM single run capacitor is the factory-specified replacement for the Carrier UPFLOW100FAUHC12 air handler unit, carrying OEM part number P291-0753 (factory-superseded by P291-0754). The run capacitor provides a continuous phase-shifted electrical charge that keeps the blower fan motor running at proper torque and efficiency. When this capacitor weakens or fails, you'll notice the fan motor humming without spinning, running sluggishly, overheating, or tripping the system into lockout — all signs of capacitor failure that this direct OEM replacement resolves immediately.

  • Specs: 7.5 MFD (microfarad) | 370V rated (440V-rated replacement P291-0754 is a factory-approved upgrade) | Oval case | ±5% factory tolerance
  • OEM vs Generic: OEM capacitors are manufactured to Carrier's exact tolerance specifications. Generic alternatives frequently run outside ±10% MFD, accelerating motor winding wear and shortening blower motor life — especially critical in continuous-run air handler applications like the UPFLOW100FAUHC12.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before touching terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter with capacitance setting. Photograph wiring connections before disconnecting the old unit. Note: Carrier sources capacitors from third-party manufacturers; the label on the capacitor body will reflect the OEM supplier name, not Carrier.
  • Warranty: 1-year OEM manufacturer warranty. Orders ship same business day from our warehouse stock.

Compatibility: Designed for the Carrier UPFLOW100FAUHC12 upflow air handler. Verify the 7.5 MFD rating and 370V (or higher) voltage on your unit's data plate before ordering. Note that P291-0753 has been factory-superseded by P291-0754 (440V), which is a direct drop-in upgrade. Questions about fitment? Our HVAC parts specialists verify compatibility before you order — reach out before checkout.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Single Run Capacitor 7.5 MFD 370V — UPFLOW100FAUHC12?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Single Run Capacitor 7.5 MFD 370V — UPFLOW100FAUHC12. 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 — UPFLOW100FAUHC12?
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?
