Abstract
A control circuit useful in commercial cooking appliances, such as deep fat fryers, having electric heating elements and separate operating and safety controls including full power transmitting contactors for independently energizing and/or deenergizing the heating elements. The simplified control is economical, but reliable, and utilizes the safety control contactor connected in series power circuit with the heating elements and a single relay to establish both an on operating circuit for normal cooking conditions where the operating control cycles on and off to maintain the desired operating temperatures and a safety circuit that deenergizes all heating elements should an overheat condition occur and further that requires manual release or reset to again render the appliance operative.
