Performing a Basic Reset
- Unplug the air fryer from the power outlet.
- Allow it to cool down completely, especially if it was recently used or overheating.
- Wait for at least 5 minutes to let internal components reset.
- Plug the unit back in and turn it on.
- Check if the error code persists. If it does, proceed to further troubleshooting.
Cleaning and Inspecting the Components
Many error codes are caused by dirt, grease, or food debris affecting sensors or heating elements. Carefully clean the interior surfaces, including the temperature sensors and heating elements, using a soft damp cloth. For stubborn grime, use a mild detergent or vinegar solution. Avoid abrasive cleaners that could damage the surface. Always ensure the unit is unplugged and cooled before cleaning. Inspect the wiring and connections for loose or damaged parts, especially around the control panel and power cord.
Checking Electrical and Mechanical Connections
Secure all plugs and ensure the power cord is undamaged. If your air fryer has removable components like racks or trays, make sure they are properly inserted and aligned. Loose or improperly seated parts can cause error signals or malfunction. If any wiring appears frayed or broken, do not attempt to repair it yourself—contact a professional or COSORI support for assistance.
When to Contact COSORI Support
If after performing these troubleshooting steps the error code remains, or if you notice any signs of damage or electrical issues, it’s best to contact COSORI customer support. Provide them with the specific error code, a description of what steps you’ve already taken, and any relevant details about your unit’s usage and condition. Professional service may be necessary for persistent or complex problems, especially those related to internal sensors or circuit boards.
