How to Fix / Troubleshooting

Safety first: Use oven mitts if surfaces are hot. Unplug and cool the unit before opening.

Steps:

1. Placement: Ensure the fryer is not placed against walls or under low cabinets, which can trap heat.
2. Inspect heat shields: Open the housing and look for metal shields around the heater and cavity. Ensure they are properly installed and not missing.
3. Check insulation: Some models use insulation between the inner liner and outer shell. Replace any burned or missing insulation with high-temperature rated material approved for appliances.
4. Verify cooling airflow: Ensure any internal cooling fan (if equipped) is operating and vents are clear.

Warning: Excessive exterior temperature can be a burn hazard; discontinue use until resolved.
