Air fryer overheats and burns food even at low temperature settings.

Safety first: Unplug the unit and allow it to cool. Overheating can be a fire risk; do not continue using the appliance until resolved.

Steps to correct overheating:

• 1. Verify settings: Confirm that the temperature and time are set correctly and that no preheat mode is being misused.
• 2. Inspect sensor placement: With the unit unplugged, remove the rear or bottom cover to locate the NTC temperature sensor. Ensure it is clipped securely near the heating area and not hanging loose or touching the element directly.
• 3. Test sensor: Disconnect the sensor and measure resistance at room temperature. A very low resistance (near 0 ohms) suggests a shorted sensor, which will cause the control to overheat the chamber. Replace if out of specification.
• 4. Check heater relay: On the main control PCB, inspect the heater relay. If the contacts are welded closed, the element may stay on continuously. Replace the main control PCB if the relay is stuck.
• 5. Evaluate high-limit thermostat: If the unit overheats without tripping the high-limit, the thermostat may be out of calibration. Replace the high-limit thermostat if it shows signs of heat damage or fails continuity tests at elevated temperatures.
