Required that i remove the built in frame and mounting. Required tamper proof socket to remove housing. I removed the old bulb and simply replaced and reverse installed the cabinet.

I removed the outer cover and exposed the inner workings. I watched a video on partselect.com to show how to remove and replace the Diode. I followed the instructions and it was very easy to replace.

Unfortunately, the diode was only part of the issue. I ended up replacing the High Voltage capacitor and Magnetron also. Those were a little more complicated but still easy to do.

Now the Microwave works just like new! Cost me less than $100 for all parts.

"PIECE OF CAKE" Removed cover,removrd bulb, replaced bulb, replaced cover. "PIECE OF CAKE" P.S. Wife is happy.

You have to remove the cover which in my case was a little more difficult because the unit is wall mounted and has a frame around it. That was the hard part. Once the mounting frame was removed, you can remove the cover and the light bulb is on the top right side of the unit. One screw removes it and the new one pops right in. Put the case back on reinstall it in the wall and voila...piece of cake.

you will a security socket T20. this unit was installed over oven, remove trim cover,remove screws holding unit in place,I used a helper to get the unit out, once out you have to remove all the screws holding the cover on,on two of the corners they use a security hex screw so you need a special socket for that. remove the door latch switch,take your time or you will break tab holding switch in. ask me how I know.but super glued broke piece in place and plugged wire back in.the new latch may have a second pin but look at old one and plug wires in the same way.the light bulb does not screw out so I had to purchase the entire unit.total cost under a $100.00 to do repair.

We got a a carbon steel but and drilled out the stews and put in regular screws. We also had trouble getting the cover back on and ended putting 2 more screws on the left side which had none. The installation was the easiest part of the installation.
