Bosch 00617116 Fixture OEM Part

One of the three-door switches had failed. In my case, 00631512 or ref 25217585 on the left front of the unit. The green button no longer "clicked". When that switch fails, one of the ceramic fuses located under the top cover at the far back of the unit is blown. Used Volt-Ohm meter to determine which fuse. Happy to have also ordered a replacement door switch Support, just in case, as I was unable to remove the failed switch from the support without breaking a key brittle plastic tab. Separately, the unit also had a dim display, ultimately discovered unrelated to the loss of power. Had just prior replaced the microwave control panel & electronic control in case that was culprit, but door switch & fuse were a separate problem. I found it easier to access door switch support with the control panel re-removed.

One of the Door switches went bad, so I decided to proactively replace all 3 door switches. Make sure to order support brackets as well, as I think it's impossible to replace switches without breaking the original bracket. For a few $$, it's not worth the hassle. Interestingly, in my case, fuse that's internal to Microwave did not get blown, only main line breaker would get tripped, but I would be doing it again, I would also order spare fuse as well. Here is how I determined that door switch is bad. With MW door open, main breaker would stay ON and MW display would light up. Once the door is closed, main breaker would be tripped, cutting the power to the MW.

The advice I got on this site from others was spot on. The problem was the microswitch on the left side of the unit (part# 00631512) as well as the fuse (part# 00631510) on the top right rear. I ended up replacing all 3 switches and plastic supports which made the job simple. I also ordered another fuse (part# 00631509) which I ended up not needing. It works great now!
