1. In a thermal range having a heating element, manually operable control means for causing selective energization of the heating element during a cooking period, timing means for timing a preselected cooking period, and alarm means for providing an alarm at the end of said preselected cooking period, improved apparatus for preventing overcooking of food by said range, said apparatus comprising:
- de-energizing means for causing de-energization of the heating element a preselected delay time after the provision of the alarm in the event said control means is not manually operated to discontinue energization of the heating element within said preselected delay time, said delay time being of a short duration preselected to avoid undesirable further cooking of the food; and

Abstract
A control for a thermal oven having a manually settable timer for establishing preselected broiling and baking times. The control includes an alarm and circuitry for sounding the alarm at the end of the timed cooking period. The control further de-energizes the heating elements a short preselected time after the time period set by the user in the event the user does not take affirmative steps in response to the alarm. The control continues to provide a reminder alarm operation at predetermined intervals, such as five-minute intervals, until such time as the user provides the affirmative input to terminate the control operation and reset the system.
