This microwave was working perfectly last night and doesn't even look like it has power today. We have done nothing to it. Please help. It is a Kenmore 721.62624200.

sounds like possible magnatron or diode thats the case its not worth repairing. but if your handy then google model nuber and get the part be extreamly careful because of the power capacitor holds extream volts. turn off and allow to sit 15min before working on

problem with switch

Hi, W/D here.

Leave unplugged for a longer time, say 5 minutes. I have done this twice on my own, and it has worked, but it took about 5 minutes.

--W/D--

We have the same exact microwave & this happened with ours just last night. I'm wondering the same if it is worth having it fixed.

first check the power to the outlet.
plug something else (that works) into that outlet to see if it has power.

Sadly your microwave has done it's last cooking. The mechanism you need to make it cook again would cost you more than a replacement microwave.

Most likely blew internal fuse. Pull the top/side cover off and check the line fuse. It should be behind the control panel in that area.

please use this link to view another servicemans explanaton of what your problem is and hopw to address. In essence, you should ALWAYs press the stop button before opening the door... Hope this helps you...

It sounds like a stuck relay or other controller problem.

I don't have the service data on this one, but there should be a schematic or tech sheet / mini-manual either on the back side, behind the controls, or somewhere else inside.

If you or someone you know can locate them and scan and e-mail or copy & fax them to me, I can probably give you further guidance.

Please feel free to contact me directly.

We're happy to help you and we'd appreciate your thoughtful rating of our answer.
