I first read where someone had the same problem. Their solution was a burned-out fuse. I ordered a new fuse...installed it and that did not solve my problem. I revisted PartSelect and read how Marla (from Arlington, TX)solved her problem. I purchased a secondary switch and when it arrived, I made a copy of Marla's instructions and followed them to the letter. I installed the new secondary switch into the secondary space, put everything back together and the oven STILL DID NOT WORK. I had to take the latching panel apart again and test each switch to see if there was another bad one. I found that the third switch was burned out. So I took the new switch out of the second slot and installed it into the third slot. I tested the switches before reinstalling the latching panel. This time everything worked. So I put everything back together, reinstalled the microwave on the wall, tested it again, and everything worked perfectly.

This went pretty smoothly. Watch the video and just follow along step-by-step and it goes well. It would have only taken about 30-45 minutes (even being careful and slow) but I ended up placing the glass twice (be very careful and triple check that all the insulation gets poked under the housing and none is sticking out). The first time I had a small piece sticking out. (Use gloves for this part so your hands don't itch). The second time I needed to redo part of it is I forgot one of the spacers on the door handle and had to get that in there so the handle worked properly. I also took the time to clean the oven while the door was off so that took some time. Total I probably had 1.5-2 hours into this project but at least half of that was me cleaning and being fussy. This is an easy repair. I'm not a confident repair person and this wasn't difficult. It was a little time consuming but well worth the cost vs calling a repair person or buying a new appliance. You do need to have a specialty star head on a screwdriver but my simple tool kit had all the tools I needed. The oven has been working great since the repair.

Threw the old one out - plugged the new one in. Steak came out just as ordered - medium rare.

replaced it with the new one.

Replaced new light housing.
Thanks to you guys for the prompt response

removed the glass turning plate. removed the broken roller guide. replaced with the new one. I am very happy with not only the ease of fixing the problem, but how quickly I got the replacement part. I will use PartSelect again!!! And I will tell my friends.

Very fast very easy. Part was exact match!

Replaced it

Replaced the fuse. Result; did not fix the problem.

Replace the fuses

I think I could have managed with just the diode but since I had to pull it I decided to replace all related parts per my research. The Magnetron more than likely was fine.

First unplugged the microwave, took top grill off, took control panel off, took wires off and used color coded tape to make sure they went back in right places, took fuse out and replaced it and put every thing back and it all worked fine and to top it off my wife did it all. So it was pretty easy.

I shut off power to the microwave, discharged the Hi-voltage capaciator and disconnected the wires to it, then removed the screw and bracket that held the capaciator in place. After removing and replacing the capaciator, reattaching wires and mounting bracket, and replacing the 15amp fuse, the microwave woked fine.

This was as easy as it gets. The whole process took seconds to complete. Simply remove the old roller and install the new one. It was wonderfully easy.
