The display on my Bosch microwave went out. This is a known problem with Bosch microwaves so I purchased a new display (incl. mainboard, old one was rel 1, new one is rel 3)) from Bosch directly . I plugged that one in but the display is still out. Hence, I suspect it's not the display/mainboard. What else could cause that? There doesn't seem to be any fuse. The breaker in on.

I have the similar built in combo unit with a range and warming drawer.

Fuses and internal switches keep failing so display wont work. I had Bosch's repair tech out 3 times to repair but he can't determine why internal switches keep failing. My unit started failing 3 months after warranty. Bosch said they would pay for parts but not service. I send parts invoices to Bosch but never heard from them after 1 year.

After 3 service calls I'm into this unit over $800 in repairs but don't want to replace with another brand because it won't match.

BUT I found an fool proof way to fix my Bosch micro wave.

Turned off the power to the unit and took a metal saber saw and cut out all Bosch microwave internals.

Then bought a cheap $50 RCA unit from Walmart and put it inside the shell of my Bosch piece of crap microwave.

It's been over a year and the RCA unit has worked flawlessly and far out performed the Bosch junk.

Interesting approach. So do you open the door and then inside you have a smaller microwave including the buttons to control it? I guess that means much reduced volume and no oven anymore.

Are there actually fuses? I heard somebody saying the same but that is actually the first thing I looked on the wiring diagram. I guess I have to take it completely out and check the back.
