As usual, I open the door, place the food in the microwave oven, close the door, then set the timing. The machine goes through the process and beeps when it's finished. The food is still frozen/cold. I've tried it on different settings and different timings and the content of the oven remains frozen/cold.

The microwave is not supposed to shut off if you have food in it. it is designed to stay running so you will not forget your popcorn.

Have a shop look at this---there usually is a recessed safety switch inside the jam that will prevent the unit from working with door open--sounds like the problem may be with it.

Check the door switches with digital meter, usually find one bad one. Set meter to ohms and test, some will be normally open and others closed, check with the door open and closed.

HELLO.

Solution to your microwave problem is given as below.

* 1 Set your Daewoo microwave on a countertop near an electrical outlet and plug it in. Open the door and place the circular roller guide in the center of the oven cavity, then place the glass cooking tray over it.

* 2 Set your food on a microwave-safe dish and then put the dish on the cooking tray and close the door. Make sure that it latches properly.

* 3 Turn the upper knob to select a power level. Power levels include "Defrost," "Med-High," or "High." If your Daewoo has a touch pad, touch the "Microwave" button once to set the highest power level. Touch it consecutive times to lower the power level.

* 4 Turn the lower knob to set the cooking time. For cooking times less than two minutes, turn the knob up past the two-minute mark, then back to the correct time. For touch pad models, enter in the cooking time with the numerical keys and then press "Start."

* 5 Open the door at any time to stop the cooking and check the temperature of your food. Shut the door to automatically continue cooking, or turn the timer knob to the right to add more time. For touch pads, press the "Stop/Clear" button, then key in a new cooking time and press "Start."

* 6 Open the door when the timer reaches the "Off" position and take out your food.

Thanks.

Hello :

This happens because of a bad door switch . The plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door .

Check also the turntable . It could be out of it's right place .

WARNING :

1:Don't slam your microwave door because this may cause the fuse to blow and this is the reason of bad door switch problem .
2: A microwave is capable of giving you a serious electrical shock even when it's unplugged , so I recommend you to call a repair technician for help .

please don't forget to rate .

good luck .

Does the food get warm at all? My suspicion is you have a bad door switch. Do you open the door while the machine is running, ever? If yes, that is not good for the little contacts on the door safety interlock micro switches. I learned this by burning mine up. The switches are less than $ at a radio supply place and typically, you can change them yourself.

Unplug the machine. Remove the cover and you will find the interlock switches on the handle side of the door, probably on the right hand side. DO NOT TOUCH THE SILVER THING AT THE BACK SIDE OF THE MACHINE - IT IS POTENTIALLY LETHAL EVEN WHEN UNPLUGGED. If you have a volt ohm meter, you can test these switches for open and closed. If they read open when the door is closed, they (or it) is probably bad.

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.

Check those three microswitches in the latch assembly.

Maybe u should contact ur retailer or the manufacture helpline and tell them your problem they might be able to tell what's wrong.
