Claim 12:
13. A control method for controlling a cooking operation of a cooking appliance including a cavity including a cooking space therein, an electronic component space provided outside the cooking space, a circuit board disposed at the electronic component space, a supporter to space the circuit board from the cavity and to support the circuit board, a temperature measuring part disposed at the supporter and supported by the supporter, and a cooling fan to generate a flow of air to pass through the electronic component space, wherein the cooling fan generates the flow of air to pass through a cool air passage that is an area surrounded by the cavity, the circuit board and the supporter, and the temperature measuring part measures a temperature in the cool air passage, comprising:
measuring, by the temperature measuring part, the temperature in the cool air passage;
determining, by a controller, whether the cooling fan has stopped operating based on a result of the measurement of the temperature in the cool air passage; and
stopping the cooking operation of the cooking appliance, by the controller, when it is determined that the cooling fan has stopped operating.
