Abstract
An auxiliary control system for an oven or similar device that is separate from the primary control circuitry and operates independently when the condition occurs that could be hazardous or unsafe. The control acts to prevent the temperature of a known point to rise above a predetermined set point, or points, and the primary circuitry failed to take corrective action.
