Hi, I was reading all the post about the Samsung Microwave's turning on by themselves because ours just started doing that. Two nights ago I heated something up and sat on my patio to eat. When I came back in I thought I smelt something hot or burning so I went into the kitchen and could feel a lot of heat from the Microwave and realized it was running but the turntable and fan was not turning or running but it was definitely getting hot. When I opened the door it stopped. I unplugged the unit and tried it again the next morning and same thing. I can plug it in and enter a cook time and it will work normally but as soon as it's done it continues to run until I open the door again. I have been leaving it unplugged and only use it if absolutely necessary. PLEASE HELP, this appears to be a very dangerous condition. The unit is only approximately 2 years old and we got it to match all our Samsung appliances (Refrigerator, stove and dishwasher). We also own Samsung Washer, dryer, 3 tv's and 2 phones. We are very loyal Samsung owners because we were so impressed by our TV's (have had 5 total over the years) performance.
