Abstract
A temperature regulating control system for an oven of a cooking apparatus and methods of making and operating the same are provided, the system having a circuit for interconnecting a power source to a load of the apparatus in a regulated manner so as to tend to provide a selected temperature output of the load for the oven, the circuit comprising a microcomputer, external components, and a voltage regulator for providing a regulated voltage from the power source for operating the microcomputer so that the microcomputer can operate the external components, the circuit having a temperature sensing unit to sense the ambient temperature of a portion of the circuit and provide a warning signal to the microcomputer that a first high ambient temperature has been sensed so that the microcomputer can shut down the external components of the system in a controlled manner before a second higher ambient temperature is sensed by the temperature sensing unit.
