Bosch 00631389 Microwave Circuit Protection Fuse OEM Part

Microwave would trip the breaker when I would press start. So I looked on Google and found on Youtube which indicated it could be a door switch. "IMPORTANT I AM AN ELECTRICAL DESIGNER/ENGINEER THERE IS A CAPACITOR THAT HOLDS ELECTRIC ENERGY EVEN WHEN UNPLUGGED DO NOT DO THIS WORK UNLESS YOU KNOW WHAT YOU ARE DOING TO REMOVE THIS ELECTRIC ENERGY SAFELY" I took apart the microwave and behind the touch panel of the microwave was the wiring sheet. There are (2) switches on the door. I took a meter and check for continuity of the switches with door open and closed. What I saw in youtube was correct, it was the middle switch which is the door monitor. The bracket that these switches mount in seemed to have a broken clip on one of the switches. So I ordered all (3) new switches and the bracket with spare fuse. When parts came in, I replaced everything verified the switches worked correctly with my meter again then did a test before remounting. It worked! $50 buck vs 200+ for a service guy or more to replace microwave.

The job was way more involved then it should be. After confirming the microwave was getting power, my plan was to look for a fuse. I pulled the microware off the wall (it's mounted above my counter top grill). Searching the housing, I did not find an access plate. I had to take off the entire housing. It's a fair number of philips head screws. Once I got the housing, I found this fuse. Facing the microwave, it's located top right above the control panel. With a multimeter, I confirmed the fuse was blown. I replaced the fuse. I confirmed the microwave would power up. I put it back together, remounted it and all has been good since. FYI - IT IS BEYOND ME why Bosch doesn't have an access panel to get to this fuse. This job would have been so much easier if they did.
