The appliance came with the new construction and it has been working well; however, there is a somewhat of high learning curve to operate it. We do not think the touch pad for cook time and function are very clear. We were confused at first when we put food in the microwave, closed the door and waited to start it for a few minutes to allow other stove top foods to finish cooking. When we tried to start the microwave, we got a "FOOD" message. Back to the operators manual. OK we finally figured out that the microwave has a safe gaurd feature that asks the consumer to check there is actually food in the microwave before it starts. Still, you might have to punch a few buttons to figure it out.
