This item worked as described. I paid more for this 'oem' probe than the generic 1 because i didn't want to chance it not working as others have reported.
- works great. tested it....snaps in, reads correctly, snaps out.

Unscrewed the control panel (2 screws), lift up and let hang, with a plan screwdriver open bracket holding the switch, unplug 2 wires, replace with new switch, plug in the 2 wires, push switch back into bracket. Then slide on the control panel, put the 2 screws back. Easy fix.

First I had to accept the fact that the unit was designed to keep non-professional people from doing any repairs. The switch was installed in such a manner that I had to break the mounting to remove the switch, then drill a hole in the mounting to secure the new switch in place.

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.

Went on Youtube and pulled up how to fix a microwave.

remov cover to check voltage and found problem at the interlock switch ohm the switch and found it was open replace both switches it work fine now

Slips in easily. Line up the tabs with the brackets and pop in.

Followed instructions that came with bulb I ordered and could not have been easier. Will use this site again.

Checked all sensors with a multi-meter, found the thermostat to be the problem, no continuity.

Changed the Temperature Sensor as you suggested, but the problem of 40 minutes to reach a temperature of 375 degrees F. remained the same.

Part Select sent the wrong part I did not realize it until prong broke off one of the bulbs. They sent 130v instead of 120v. Return bulbs awaiting resolution.

change bulb

Remove oven light lens cover, remove the bulb and replace it with a new one.
