I exchanged this product once due to issues with the door, and I should have just returned it. The door release has been problems from the moment I bought it. It is a poor design. You can't just select the power level you want, you have to press the button as many times as needed to reach the % you want. To get to 30% it takes 8 pushes of the power level button! I have always liked GE products, but DO NOT buy this one.
