OEM Carrier Capacitor for Model FPMBNU018T00ACAA — Part 202401100409

This is the factory-specified OEM replacement capacitor for the Carrier FPMBNU018T00ACAA. The capacitor is a critical electrical component responsible for storing and releasing the charge needed to start and run your system's motors. When a capacitor begins to fail, symptoms typically include a humming sound with no motor movement, the unit failing to start, short-cycling, or the compressor or fan running sluggishly before shutting down. Replacing a failed capacitor promptly prevents compressor burnout and costly secondary damage.

  • Specs: OEM Part Number 202401100409 | Factory-matched MFD and voltage rating | Engineered to exact Carrier tolerance specifications for the FPMBNU018T00ACAA
  • OEM vs Generic: This OEM capacitor is built to Carrier's exact ±3% MFD tolerance. Aftermarket alternatives commonly run ±10% or wider, which accelerates motor and compressor wear and can void equipment warranties.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Recommended tools: 1/4" nut driver, needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal to ensure correct reinstallation.
  • Warranty: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our dedicated HVAC parts warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier FPMBNU018T00ACAA. Always verify your unit's data plate MFD and voltage ratings match before installation. Our parts specialists are available to confirm fitment before you order — same-day shipping available on all in-stock orders placed before 3 PM EST.

Frequently Asked Questions

Does this Capacitor fit my Carrier FPMBNU018T00ACAA — Part 202401100409?
Yes. This is the factory-specified OEM capacitor for the Carrier FPMBNU018T00ACAA — Part 202401100409. 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 FPMBNU018T00ACAA — Part 202401100409?
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?
