ABSTRACT:
The invention relates to a method and a circuit arrangement for preventing overheating of a cooking appliance. The arrangement includes a power circuit with a heating element and a control circuit with a coupling switch. The control circuit and the power circuit are coupled by the coupling switch. The arrangement further includes a safety switch to the control circuit. The coupling switch interrupts a power supply to the power circuit to the heating element when a limiting temperature in the cooking appliance is exceeded.
