Abstract
An appliance control protection apparatus for a glass ceramic cooktop is constructed with a double wall housing and a low voltage cooling fan. The double wall housing is comprised of a first inner wall and a outer wall and prevents the transfer of heat from the heating elements in a glass ceramic cooktop towards the electronic control unit. The first inner wall is adhered to the underside of the ceramic glass panel of the cooktop and the outer wall snaps into position over the first wall, resulting in a space therebetween for insulation. Additionally, the control housing is provided with a low voltage fan that convects heat away from hot spots formed on the electronic control unit toward other components within the control housing. The low voltage fan operates in response to certain operating temperatures within the control housing as detected by a heat sensor.
