Post 42 microwave installation

The microwave in my new-to-me post 42 wouldn’t power up. Took me a while to figure out how to get it out and I figured I’d share a pic so others could see how it’s installed.

The microwave is mounted on a piece of plywood with cut-outs for the feet. The plywood has a finished bottom trim piece mounted to it.

The plywood mount is secured via a few screws that are accessed from underneath the countertop by removing the drawer underneath the microwave.

So, to get the microwave out, you remove the screws securing the plywood mounting block to the counter. Then, slide the microwave and plywood piece out together. It’s a little tricky because it runs into the sink faucet eventually but it will lift out. There was also a metal bracket on top of the microwave that was secured by some fasteners coming down from the cabinet top above the microwave. It’s unclear how/if this was doing anything because i unscrewed it before I could see.

The microwave issue turned out to be a blown ceramic fuse. It does appear sharp still makes a microwave/convection combo with matching dimensions for ~$500 but fortunately it looks like the fuse will get me back in business. Hope this is helpful to someone else down the line.

chainsaw also would have worked.

Unfortunately turned out to be more than the fuse. Changed it and it just blew again as soon as I started it.

Door switches read 0.3 ohms closed which is I guess ok.

I got weird readings on the high voltage capacitor though. I bought a new southwire meter with a capacitance test function. Testing the capacitor for a brief second it gives a reading then switched to “OL”. This reading isn’t explained in the manual but on a fluke meter apparently means the cap is bad.

I can’t find an exact replacement for the cap so I finally gave in and ordered the replacement model from sharp, which is supposedly the exact same dimensions (but is quite pricey for a microwave)
