Oven displays E10 and shuts down shortly after starting, cooling fan may run at high speed.

Safety first: Disconnect power and allow the oven to cool before removing any covers.

• Check installation: Ensure the oven is installed with correct clearances and that cabinet cut-outs do not block the control panel vents.
• Inspect control compartment: Remove the top/front cover to access the control board area. Look for dust buildup, insulation out of place, or wiring obstructing airflow.
• Locate control sensor: Some Tristar ovens use a small NTC sensor or thermal fuse near the control board. Check its wiring and connector for damage or disconnection.
• Replace faulty sensor: If the control temperature sensor is open/shorted when tested with a multimeter, replace it with the correct Tristar control compartment sensor.

If E10 persists and the board shows signs of heat damage, the main control PCB may need replacement. Consider professional service for persistent overtemperature faults.
