Bosch 00631510 Microwave Fuse 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.

I found several similar stories on AppliancePartsPros website related to this type of Bosch Microwave power failures, so I called their customer service to make sure that I ordered the correct parts for my repair. The agent was EXCELLENT and went above and beyond by checking all available parts diagrams to verify the parts I needed. Of the 3 switches in the door closing mechanisms one of the 2 on the left side of the microwave (as you look at it) was bad and the 1 located on the opposite side was bad. I needed 2 of the switches with a red button and 1 with a green button. (1 each red+green on left / 1 red on the right). Do get the supports for each sides switches. I ordered both and wound up using one for right side when pin that switch goes on broke. Also the fuse that blows is located in right rear corner of unit (there are 2) 1 was good / 1 bad. In addition to removing top of unit removing control panel allowed better access to switches. A lot of screws to remove but overall an easy repair.

First ordered line fuse. After replacing, breaker tripped immediately indicating a short somewhere. Using the servicing guidance located inside the microwave, I used a multi-meter to test each component. Problem ended up being one of the three door micro-switches. Switch was supposed to be open when door was closed, but remained closed either way. Ordered switch and replaced. Problem solved. Biggest obstacle was microwave was part of in-wall combination oven weighing 340 pounds. It had to be completely removed from wall.

I had to take the combo oven and microwave out and operate through the top metal cover on the microwave.

Ordered parts that I received next day via expedited order. Replaced and returned to service.
