OEM Carrier Run Capacitor CAP003 for Model FB4BNF024008AAAA

This OEM Carrier run capacitor is the precise replacement for your Carrier FB4BNF024008AAAA fan coil blower motor. The run capacitor delivers the continuous phase shift the motor needs to start smoothly and run efficiently during every cycle. A weak or failed capacitor commonly results in a humming motor that won't spin, hard or slow starts, motor overheating, or increased energy use. This factory-matched part provides the exact microfarad (µF) and voltage rating to keep your motor running cool and at full torque, prolonging its service life. Replacement is an easy-to-moderate DIY job — discharge the old capacitor safely, note the terminal wiring, and install the new unit, usually under 20 minutes with insulated hand tools. Always cut power at the breaker and discharge the capacitor before touching any terminals. The genuine Carrier component ensures correct specifications and reliable, long-lasting performance over cheap universal options. We keep this part in stock and ship same-day on all orders placed before 3PM CST, so your air handler is back in service without delay.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FB4BNF024008AAAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FB4BNF024008AAAA. 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 FB4BNF024008AAAA?
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?
