Step 1: Power Cycle Your Air Fryer
- Unplug the air fryer from the electrical outlet.

Ensuring cleanliness can resolve errors related to temperature sensors or overheating.
Step 3: Inspect Heating Elements and Sensors
- Ensure the unit is unplugged and cooled down.
- Visually examine the heating element for signs of damage, such as cracks or debris.
- Check temperature sensors for dislodgement or dirt — clean gently if needed.
