Unit shuts off randomly during cooking and restarts or remains off without showing an error.

Safety first: Unplug the fryer and allow it to cool before inspection.

Steps:

• 1. Improve ventilation: Ensure the fryer has adequate space around it and is not enclosed.
• 2. Inspect power connections: Open the housing and check all mains connectors, including the power cord entry, internal terminal blocks, and board connectors. Tighten or replace as needed.
• 3. Check thermal cutoff: A failing thermal fuse or thermostat may open intermittently. Test continuity when cold and after heating (if possible). Replace if unstable.
• 4. Examine control board: Look for cracked solder joints on the power relay or mains input. Reflow or replace the board.
• 5. Test under load: Reassemble and run a long cycle while monitoring. If shutoff persists, further board-level diagnosis or replacement is needed.

Warning: Random shutoffs can indicate overheating; do not ignore this symptom.
