ABSTRACT:
A glass ceramic hob electric cooker is provided on each of the radiant heaters thereof with a temperature responsive element such as a bi-metallic switch or a thermistor, which element is arranged adjacent to or within an opening which communicates with an enclosed chamber formed between the heater and the underside of the glass ceramic cooking surface. When the heating element of the heater is energized, hot air issues from the opening and impinges on the temperature responsive element thus heating said element. A warning lamp is connected with the temperature responsive element to indicate when said element and thus the glass ceramic cooking surface is at or above a safe touching temperature of 50.degree. to 60.degree. C.
