We purchased this combination oven/microwave in 2012 and the control unit has now failed (part # [protected]). Our repairman ordered a new module in august 2020 and after many delays we've been told it is now a discontinued part. We're very upset that we can't repair the oven, and now are being told to replace it will cost about $3600!!! We're hoping that someone at bosch can find this part, or a replacement, so we can fix our oven and not have to replace it all. If must exist somewhere, or a replacement. If not, we need a refund or discount on a new unit.
