A microwave oven comprises a cooling system and a magnetic shield system applied to a plurality of circuit elements. The cooling system comprises a compartment through which air can pass. The compartment is formed by at least one printed circuit board carrying a plurality of circuit elements and a supporting member for supporting the printed circuit board. The circuit elements are cooled by the flow of the air. In addition, the circuit elements are magnetically shielded from a magnetic field generation device such as a magnetic card reader/writer and a high voltage transformer by a shield member. It is possible that the circuit elements are protected from very large quantities of heat emitted by the high voltage transformer. The magnetic card reader/writer may be provided for reading/cooking program information from a magnetic card and writing the same on it. The microwave oven should be controlled according to the cooking program information for cooking purposes.
