Claim 10:
11. A cooking appliance comprising:
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,
wherein the cooking appliance further comprises a controller configured to control a cooking operation of the cooking appliance, and
the controller is configured to stop the cooking operation of the cooking appliance when the temperature measured by the temperature measuring part exceeds a predetermined temperature,
wherein the predetermined temperature is a highest temperature among temperatures that can be measured by the temperature measuring part during an operation of the cooling fan that indicates a failure of the cooling fan.
