The problem I am having is that the microwave will totally shut off after heating something going to the end of the set time. I mean no lights no display nothing. But if I unplug and replug it is fine for one or two more uses then the same thing happens. Don't ask why I thought to unplug I guess the first time I thought it was the outlet. This has been going on for a long time now. Honestly I have not had the money to buy a new one and start inquiring on repairing it. Any suggestions...
