There may be many reasons for this. But the most important and generally found reason is the door of the microwave oven is not closed properly, means that the spring attached with the door may be jammed or loosely working. When the microwave door is closed the spring inside the door pulls the door hooks properly to give sensors in the door to start micro oven. It may be possible that one of the springs or both the springs are not working properly. Inform your technician to check door of the micro oven properly.
