S. HI-LIMIT THERMOSTAT (GAS AND ELECTRIC MODELS ONLY)

The hi-limit thermostat is another safety device that we use on gas and electric models. The hi-limit is located in the burner or oven area. The hi-limit switch cuts off the heat, if the temperature exceeds 290° for electric models or 330º for gas models. The only way this device would shut off the heat, is when the airflow changes to the extent of making the flame brush up against it.
