Nuwave air fryer fan does not run; unit heats but there is little or no airflow.

Safety First: Unplug the air fryer and allow it to cool. Do not operate the unit without a functioning fan; this is a fire risk.

Step-by-step checks:

• Listen for fan: Start a short cook cycle and listen closely. If you hear the heater click on but no fan noise, shut the unit off and unplug it.
• Inspect fan visually: Remove the basket and look up at the fan. Check for heavy grease or debris that could prevent rotation.
• Manual spin test (advanced): With the unit unplugged and cover removed, try spinning the fan by hand. If it is stiff or stuck, the motor is likely bad.
• Check wiring: Inspect the fan motor harness and connectors for disconnection or damage.
• Replace motor or board: Replace a seized or open-circuit convection fan motor. If the motor tests good but never receives power, the main control board fan driver is likely faulty.

Warning: Continued use without airflow can overheat the heater and surrounding plastic, potentially causing fire.
