Tech notes
Unlike almost every other microwave, this one is worth repairing at nearly any reasonable cost, the appliance runs well over a thousand dollars and it is built into cabinetry, so replacement means joinery as well as an appliance. The drawer mechanism is the part that distinguishes it, and it is the part most likely to need attention over a long life.
