Our Samsung microwave turns on when the door closes and also starts up by itself. Upon returning home one day it was running causing a fire hazard with our two dogs in the house. This is a well documented factory issue and Samsung did not want to pick up the cost to repair. They told me I had to prove how long ago we purchased it in order to determine whether or not they could help us. I told them we are loyal to Samsung and love the brand...phones, tv's & washer/dryer and that they were going to lose two customers for life. They did not care they were losing two customers that would have spent thousands on their products in the coming years just to save the cost of repairing an issue that we and hundreds of other Samsung customers have experienced. We cannot begin to convey how disappointed we are in Samsung. They showed absolutely zero customer loyalty and went by the book, not by what was right. As a result, I will no longer recommend or purchase Samsung products.
