This is another problem. Once a machine is a few years old, they stop making replacement parts. Fortunately, some companies will sell stocked parts or cheap knockoffs from China so you don't have to buy the new machine right away. My microwave is part of a dual oven combo and it is designed to fit above the electric over in a cabinet that had to be built around the oven combo. When the microwave broke and I got the estimate for the repair I looked into buying a new microwave but the company, Bosch, no longer made that same microwave or another with the same dimensions. I would have had to get a new oven and microwave, ka-ching, AND get the cabinet replaced too, which of course would not match the finish of the other cabinetry. Screwed! I was forced to shell out for the repair of the microwave, where they used a different part to repair it because Bosch no longer made the old part. Now my microwave doesn't work right. For some reason the first 20 seconds of operation it just turns the turntable but doesn't actually heat anything.
