Looking at the service manual at our site, that would be a failure in the "motor relay" (relay 4) or one of the components that drive that relay, such as transistor Q8.

The part numbers for this relay are OJ-SS-124LM (generic) 5SC0101405 (Daeweoo).

Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

SOURCE: looking for a user manual for a daewoo microwave

If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers for spare part supplies as required.

Just Google the manufacturer's name and follow the links. Make certain you are directed to the manufacturer's web site as some search engines direct you to other sites and they charge for the information that is normally free of charge.

I hope this helps.

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.

YOUR SAFETY IS PARAMOUNT

This is a job for a professional but if you are safety clued up, here's instruction.
Make sure the !!!!any capacitors are discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

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


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.

My koc-81h4t daewoo microwave convection oven is blowing fuse,i tried to isolate the high voltage area,the griller is working fine,but when im tryin to use the convection,fuse still blows,take note that...


Possible that the high voltage CAPACITOR or the transformer is short. So you need to isolate the total HT circuit to confirm , if the connection to the magnetron was removed.
Also check for any short on the surger protector at the front end of the supply.

My Daewoo microwave is model KOC-9Q1T/KOC-9Q1TSL I notice that the plastic frame around the top of the door is wrinkled, as if it has melted. I have photos of this if you need them. Please let me know 1....


Plastic will melt but the door frame is metal and will not. So there is no safety issue here, just looks.
One could replace the door assembly if required. I would leave the door open after convection cooking to let the heat escape without heat build up causing the plastic to mishape.
