On new years eve, the microwave portion of my Thermador double wall oven died. I am trying to find someone to repair it. In the event that I can't, I'd like any feedback from others around replacement options. My existing unit is a 24" wide with extremely limited expansion options due to cabinetry and the refrigerator/freezer. One unit that is appealing it a Miele unit. Does anyone have any feedback on the Miele wall ovens?
