    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?

    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?

    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.

    Our Daewoomt1510w does the same thing, should we trash it , or try to fix it? I have no money to buy another one , or pay someone to fix it . Is it a problem that can easily be fixed by someone with no handyman skills?

When it cuts off, does it act like someone just hit the stop button or do you actually have to reset the clock as if it got unplugged?

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:

Set clock on Omega 00652XN oven it has 3 buttons

Turn the oven off at the wall. When you turn it back on the clock will flash. Use the + or - to adjust the clock then use the middle button to scroll through the duration, start and end times of the auto cook function until you end up back at the clock. The oven symbol will always be displayed in clock mode unless the auto cook function is set.

Hope this helps.

Unit operates does not heat anything

A defective diode or magnetron can cause the oven to sound differently and not to cook.

MW8119SB cooks when door is closed regardless of settings

Clear the cook cycle when you remove the food. Some microwaves pick up where they left off, so you don't have to keep pressing buttons.

We have a frigidaire microwave and in the middle of cooking, the motor stopped. The clock and cook time continued to work, but no heat. We've tried using at half power, on defrost, etc. but nothing seems...

What you are saying the microwave stop work like heating,but but the clock counts down.If it is stop heating then there is a rest on or near the magtrogron.Once it cools down it start back heating.Open and close the door will reset power to the magtrogen{sorry about the spelling].Look for loose connector,or replace the click zon it should have a small red buttom on it.

Does not cook - time counts down extremely fast

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.

Unit makes a loud buzzing sound whenever the unit has power.

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

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

Troubleshooting my Kenmore 721.66227

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.

Otherwise, when you hit Start to cook, do the inside light and turntable come on?

Any unusual noises?

Is it louder or quieter than usual?

Since it's less than one year old, it should be fully covered under warranty. I'd suggest contacting Sears to get it fixed free.

Please try on some other power point as if there is loose contact or sparking in point which cause to switch off as soon as you start because of heavy current drawn by oven and clock also resets. If not solved even then must have some short circuit or over loading in timer circuit or magnetron. in this case you have to call for a service engineer.
