Abstract: A top hood for covering food in a microwave oven is provided. The top hood (H1) includes a microwave transparent wall structure including a side wall (SW) and top part (TP). The side wall (SW) and top part (TP) define the internal area (IA) covered by the top hood (H1). Attached to the wall structure of the top hood (H1), the top hood (H1) includes a temperature sensor (TS) for measuring the temperature within the internal area (IA) covered by the top hood (H1). The top hood further includes a wireless transmitter (WT) for transmitting the measured temperature information to an external display unit (DU).
