Air fryer runs but does not heat; fan operates and timer counts down, food remains cold.

Safety first: Unplug and allow the unit to cool before opening.

• Verify settings: Confirm that a temperature above ambient is selected and that the unit is not in a fan-only mode (if available).
• Listen for heater click: At the start of a cycle, you should hear a relay click. Absence may indicate a control issue.
• Internal checks (advanced):
  • Access the heater terminals and check for loose or burnt connectors.
  • Test continuity of the heater and thermal fuse with a multimeter.
• Replace failed parts: Replace the heating element or thermal fuse if open. If both are good, the main PCB/relay is likely faulty.
