Basic Troubleshooting Steps
- Unplug the air fryer and wait at least 5 minutes before plugging it back in. This can sometimes reset internal components.
- Check the power outlet by plugging in another device to confirm it’s working properly.
- Inspect the power cord and plug for visible damage or loose connections.
Inspecting the Heating Element and Sensors
Open the air fryer’s basket and interior panel (if accessible) to examine the heating element and sensors. Look for signs of debris, grease buildup, or damage. Carefully clean any residue with a soft cloth and a mild cleaner. Ensure that sensors are properly connected and not dislodged. Damaged or disconnected sensors often trigger error codes like E1.
Resetting and Testing the Device
- After cleaning and inspecting, press and hold the power button for 3-5 seconds to perform a soft reset.
- Plug the unit back in, turn it on, and see if error codes persist.
- If error codes remain, try performing a factory reset if your model supports it, or unplug for an extended period (up to 30 minutes).
When to Contact Support
If you’ve tried all troubleshooting steps and the error codes still appear, the issue may be internal or hardware-related. Contact COSORI customer service for assistance or consider professional repair. Avoid attempting to disassemble the unit further, as this can void warranty or cause safety hazards.
