Unplug and Power Down
- Disconnect the air fryer from the power outlet.
- Allow the unit to cool down completely if it has been used recently.
- Wait at least 5 minutes to ensure internal components reset.
This step prevents electrical shock and resets the internal electronics, which may clear transient errors.
Clean and Inspect Critical Components
- Remove the basket and any accessories carefully.
- Check the temperature sensors, heating elements, and fan areas for dust, grease, or debris.
- Use a soft, damp cloth or a soft brush to clean sensors and the interior surfaces gently.
- Ensure that air intake and exhaust vents are unobstructed.
Dirty sensors or blocked vents can cause false error codes or overheating warnings. Cleaning these parts often restores normal function.
Reset the Device
- After cleaning, reassemble the air fryer securely.
- Plug the unit back into the power outlet.
- Turn it on and attempt to run a simple cycle or preheat function.
- If the error persists, try a factory reset if your model supports it—check the manual for specific instructions.
Resetting clears temporary glitches and may resolve minor software errors causing error codes.
Check for Overheating or Electrical Faults
Ensure the air fryer is placed on a heat-resistant, flat surface with sufficient space around it for ventilation. Avoid using extension cords or damaged outlets. If the error code relates to overheating, check that the vents are clear and that the ambient temperature isn’t too high.
If errors continue despite these steps, consider contacting COSORI customer support or a qualified technician. Persistent error codes may indicate a faulty sensor, wiring issue, or internal component failure that requires professional repair.
