Air fryer runs but does not heat (fan runs, no warmth inside).

Safety first: Unplug and allow the unit to cool completely before opening. Heating circuits carry dangerous voltage.

• Check settings: Confirm that a temperature above room temperature is selected and that the timer is set.
• Inspect heater: Access the heating element and look for breaks or burn marks in the coil.
• Test thermal fuse: Locate the thermal fuse near the heater and test for continuity. Replace if open.
• Measure element resistance: Use a multimeter to check the element. Replace if open.
• Control board: If the element and fuse are good, the heater relay or triac on the control board is likely faulty; replace the main control PCB.
