I have owned microwaves since they first came out. This model MWG9115SB worked fine until yesterday. I am a disabled senior citizen and I am also almost totally deaf. I cannot hear this microwave from upstairs. The most bizarre thing happened yesterday. I heated something for 2 minutes. I t ran the time and beeped. I took the item out and everything was fine. 5 hours later, I went downstairs and found the empty microwave RUNNING ON ITS OWN. The clock was working and showed the correct time. I had not set it to do anything. It did not have a countdown. I have no idea how long it was running. I just unplugged it. Since you cannot run the microwave empty, I am sure that it is ruined and 1 1/2 years after purchasing, I will have to now get a new microwave. This is absurd. I only get $909 per month to live on. I cannot afford another. This one is obviously defective and it cannot be the only one with this problem.
