My microwave oven suddenly stopped working. It produced an odd smell when I last tried to use it. When I press the one minute cook button, it counts down until 38 seconds are left and then shuts off. However, the contents of the oven are not heated in the process. The oven is not very old, so I am surprised I am having a problem already. Can anyone suggest possible reasons for this occurence? If so, what are the possible solutions? Thanks - Doug
