Keep your air handler motor running efficiently with this genuine OEM Carrier run capacitor, engineered to factory spec for the FB4ANB048015ADAA fan coil unit. A run capacitor delivers continuous voltage to the fan and compressor motor, improving efficiency and shielding the motor from overheating and burnout.

This OEM replacement carries the exact microfarad (µF) and voltage rating your unit was designed around, eliminating the compatibility risks of universal parts. The repair is moderate and DIY-friendly for anyone experienced with HVAC electrical work — shut off power and discharge the old capacitor before removal.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FB4ANB048015ADAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FB4ANB048015ADAA. 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 run capacitor on my Carrier Model FB4ANB048015ADAA?
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 run 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 run 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?
