I have only had this microwave for 3 months and for the past 2 months I haven't been able to use it conveniently. One day the microwave shut off and so I unplugged the microwave and plugged it back in. When I did this the fan vent turned on automatically on the highest setting and when I hit the vent button to turn it off, it only went between levels low and high. Now I have to leave the microwave unplugged until I want to use it and then I have to plug it back in and have the vent fan on while I microwave my food. How annoying is that?! And it's only a few months old! Such an inferior product. I don't want to hear 1 more Samsung rep tell me to unplug the microwave. Anyone else having the same problem?
