Khmc107b (not a bt): lost power, won't start again

Should be one of these. I expect manuals have specs. Cut and paste into your browser address line.

Not enough venting. Imagine putting your hair dryer on full and putting it that cabinet. Would your venting keep it cool? Your microwave oven uses about the same current

Sounds like the electronics overheated. You'd have to pull it and examine the insides to see what has gone bad. It could be pretty much anything.

Hi Ben,
This has got to be an intermittent power to the control PCB problem. The control board asking to set the clock means that the CPU has been reset by losing power. First, make sure that the problem is not the outlet by plugging in a small lamp or digital clock to see if it works intermittently or resets. Leave it plugged in for at least 24 hours.
(If using a lamp, put in a small 20 watt light bulb or CFL).
It could also be a bad connection to or at the fuse holder in the microwave oven. If all of the wiring and connections look good, it's most likely a bad connection on the control PCB probably around the transformer on the board. Be careful.......

see the information attached and test the main component for SHORT. God bless you

It sounds like it could be just a bad crimp connector supplying power to the whole system, which would have to be the fuse holder on the mains input panel.
Worth a look!

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

Then let us know if the hard reset does not fix it. and please reply back with your brand and model number so we can help you.

May be a little late, but... 1. Press Power Level button for approx 5 seconds - you get the 12 hour clock 2. Press again for 24 hour clock 3. Set hours using the 10 min and 1 min buttons 4. Press Power level button 5. Set minutes using the 10 min and 1 min buttons 6. Press Power level button And you are done

first of all your mwave needs to be properly ventilated .the problem is your magnetron when heated the thermal cutof switch cutts out power to magnetron.works again when cool.change magnetron
