also have the same problem on a daewoo combi microwave. after a few seconds the microwave stops as if someone has opened the door or pressed the stop/cancel button. Keeps doing it until I pull the plug for 20 seconds, then it is alright for anything up to a week.

We have a similar problem. With our Daewoo microwave KOC-8H4T Stainless Steel.
I placed a cup of coffee (on what must have been) exactly in the center of the turntable to reheat it, set the timer for 30 seconds and it shut off after 7 seconds or so.... repeated attempts had the same result, shutting off within 7-12 seconds..... each time I had to reset the clock...! I tried resetting the microwave by pulling the plug out.... but it did not help.
Then I tried it again, placing the mug of coffee off-center on the turntable and now it seems to work fine....!!
Perhaps some sort of sensor that cannot detect the cup in the microwave when it is in the middle of the turntable, the cup I was using had no handle on it....
I did manage to get the microwave to hang completely, where it would not respond to any buttons, the display showed '0', the light was on, the turntable was rotating, but nothing else happening....
I did also get a fault code that came up on the display IA-18 I think it was, wish I had written it down......
Has anyone heard from Daewoo about these problems?

We have had the same problem. We installed this microwave about a month ago and use it a couple of times a day. Today when we went to use it, it started all right but then cut out in the middle of the programmed time. We checked the breaker box, the outlet, and anything else that we could reach. Nothing. We let it sit for about 15 minutes, plugged it back in, and all was fine. This might be some sort of Daewoo defect. It is NOT the door causing the problem. It was NOT an external power failure. It is definitely an internal problem. Any idea what it could be?
If it's the first one, then it's probably a bad door switch or door switch mount, or possibly a bad connection on the circuit board or a failing circuit board relay.
If you wiggle the door up and down and in and out very slightly, does it fail? If so, this is more eveidence pointing to the door switch or door switch mounts.
If it actually resets so you have to set the clock again, then you are losing power somewhere. This could be caused by a bad connection at the fuse holder, at the magnetron or other thermostat / thermal cutout, or on the circuit board.
If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and
disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk
