Abstract
A system and method for controlling heater element operation in an oven includes a proportional heater signal generator that is mounted in associated with an oven operational mode switch. The signal generator operates in a sub-interval about a mode indicator to generate a proportional signal for controlling a heater element. The proportional signal may be used to alter the input voltage or timing control of the heater element.
