Air fryer heats but the fan does not run; food burns on top and cooks unevenly.

Safety first: Unplug the air fryer and allow it to cool completely. Do not operate the unit without a working fan; overheating and fire risk increase.

Step-by-step checks:

• Confirm symptom: Start a short cook cycle and listen. If you hear the heating element click on but no fan noise, stop the cycle and unplug.
• Inspect fan area: Remove the rear or top cover to access the fan. Look for foil, parchment, or food debris jammed in the blades.
• Manual spin test: With the unit unplugged, spin the fan by hand. It should move freely. If stiff or grinding, the motor bearings are likely worn out.
• Check wiring: Ensure the fan motor connector is fully seated on the motor and control board ends.
• Component replacement: If the fan is seized or noisy, replace the convection fan motor assembly. If the fan spins freely but never runs, the control board relay may be faulty and the board may need replacement.

When to stop: If you are not comfortable accessing internal components, contact a technician. Do not continue using the air fryer without a functioning fan.
