Abstract: A cooking appliance is disclosed. The cooking appliance includes an electric heater for heating an object to be cooked, a mechanical manipulation unit connected to the electric heater for allowing a user to input primary ON/OFF of the electric heater and power of the electric heater, a normal open type DC relay connected to the manipulation unit, and a controller for controlling the DC relay to control secondary ON/OFF of the electric heater based on sensing of a primary ON state of the electric heater by the manipulation unit (a state in which the manipulation unit is operated).
