Air fryer overheats; food burns quickly even at normal settings.

Safety: Unplug immediately if you suspect overheating. Allow to cool fully.

• Check for sensor detachment: Open the housing and verify the NTC sensor is firmly attached to the heater shroud. Reattach with the original clip or a high-temperature clamp if loose.
• Inspect sensor wiring: Look for pinched or shorted sensor wires. Repair or replace the sensor harness if insulation is damaged.
• Test sensor resistance: At room temperature, measure sensor resistance and compare to spec. A very low resistance may indicate a shorted sensor.
• Check heater relay: If the heater remains on even when the unit is turned off or reaches set temperature, the relay on the control PCB may be welded closed. Replace the PCB.
• Verify thermal cut-out: Test continuity of the thermal cut-out thermostat. If it never opens at high temperature (requires controlled heating to test), replace it.
