GE profile PEB7227AN3DD suddenly stopped working

My microwave that was a builder upgrade stopped working. It’s one year old according to the manufacture plate in said oven, and one year one month of use. I had a ge in another house and when it happened at the one year mark, it was the magnatron! Had to buy a whole new one. I’m praying this isn’t another one. Ge wants $117 to just look at it. Help
