Daewoo Microwave Rangehood

I turn the microwave to any setting and it runs through without a problem, but immediately after it finishes cooking the screen goes blank and none of the controls work. After about 10 minutes everything comes back on again. Any suggestions. The unit is brand new.

GE Microwave (JVM1860CD001) control board buzzes.

see this causes and fix it. God bless you
Magnetron If the microwave is loud or noisy only when cooking, the magnetron tube might be defective. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. Under normal circumstances the magnetron is nearly silent. However if it is damaged or nearly burned out it can begin emitting high pitched or growling noises. It's not normally dangerous to use a microwave oven when it makes these noises, but they are an indication that the magnetron is almost dead and will need to be replaced.
Exhaust Fan Motor If the microwave is loud when running the fan motor might be
Stirrer Motor If the microwave is loud or noisy the stirrer motor might be worn out. The stirrer is a metal blade which slowly turns around, deflecting the microwave energy in a random pattern inside the microwave oven. As the motor nears the end of its useful life it begins to make grinding noises. The microwave will not heat food evenly without this stirrer, the motor should be replaced.
Turntable Motor If the microwave is loud or noisy the turntable motor might be worn out. This is a common problem and relatively easy to replace.

Burns my popcorn constantly. is there a different setting i can put it on?


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.

Occassionally (about 5% of the time) the microwave continues to cook and buzz after the timer has run out and the fan stops running.

sounds like the program bord is faulty,, when your finished cooking leave the door open a little that will save the microwave from trying to cook nothing?

Arcing while cooking.

Make sure the inside of the oven is clean and the waveguide cover on the right wall of the oven is especially clean and not damaged. Don't ever run the oven without food in it. If the waveguide cover is damaged it will arc no what but you can probably get a replacement for a few bucks. The magnetron may already be so damaged that it'll never work right again.

Tappan TMV151FS over range microwave starts to work and then dies

Never run the microwave without a load (something to heat)!!! That kills the microwave generating parts.

Sounds like a 'thermal' protect switch is activating after running. Make sure that (if the unit is mounted in a cabinet) that there is sufficient space around the unit for proper air flow and that nothing is blocking the vents. Try setting it on a counter top and heat something. If it works properly and doesn't shut off, the venting space is the problem. You may have to have the cabinet that it sits in redesigned for more clearance.

Daewoo microwave that won't cook

More than likely a door switch inside the unit is misalligned or faulty. Crack it open and check for proper allignment and good open/closed circuits with a VOM.

Time Run but microwave does not cook

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. Other times, it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

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