OEM Carrier Single Run Capacitor 7.5 MFD 370V for Model UPFLOW100HCU12A

This OEM single run capacitor is the factory-specified replacement for the Carrier UPFLOW100HCU12A upflow air handler. Originally supplied under part number P291-0753 (now superseded by P291-0754), this oval-style 7.5 MFD 370V capacitor is responsible for sustaining the blower motor's continuous operation once it has started. When it degrades or fails, symptoms include a blower motor that hums but won't spin, sluggish airflow, intermittent shutdowns, or a tripped thermal overload on the motor — all signs the capacitor can no longer hold its charge.

  • Specs: 7.5 MFD (microfarad) | 370V rated (440V-rated successor P291-0754 is a direct upgrade) | Oval form factor | OEM-matched ±5% tolerance for precise motor performance
  • OEM vs Generic: The OEM Carrier capacitor is manufactured to exact factory tolerances. Generic capacitors often drift outside rated MFD values within the first season, increasing motor heat and accelerating winding failure in your blower motor.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting the old unit.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier UPFLOW100HCU12A upflow air handler. Note: P291-0753 was discontinued in November 2020; the current OEM equivalent is P291-0754 (440V), which is a direct drop-in upgrade. Always verify the MFD rating on your unit's data plate before ordering. Need fitment confirmation?

Frequently Asked Questions

Does this Capacitor fit my Carrier UPFLOW100HCU12A?
Yes. This is the factory-specified OEM capacitor for the Carrier UPFLOW100HCU12A. 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 UPFLOW100HCU12A?
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?
