Time for a new microwave.

What fuse do you want to replace?
If it is an internal fuse inside the microwave case, DO NOT TOUCH IT, unless you are qualified to do so, because the HIGH Voltage capacitor inside can store enough HIGH VOLTAGE for long periods, enough to kill you.

Hi. The fact that the fuse blows when the door is closed is quite logical. There are safetyswitches preventing the oven to start with an open door. As to the fuse blowing, There are 3 possibilities: the High voltage trafo is defective, the voltage doubler diode or the capacitor are defective. You must be VERY CAREFULL when working on these parts: the voltages are LETHAL.

This is most likely the fuse in the high voltage magnetron circuit (that is the microwave generator). This fuse is usually inside an inline plastic case that can be opened for replacement. Don't attempt this unless you have some experience and can work from just this clue. Otherwise take it to a professional repair shop.
I would guess it is only worth repairing if you think this may have been caused by overloading the oven (i.e. putting something metallic in the oven). If not then the fuse may have blown due to another problem and you would be better off to buy a new microwave oven.

It's normally in the power plug. you probably would need a screw driver to take the fuse out. check the AMP and make sure while replacing the correct AMP fuse is placed. hope that helps.

it could be a thermal fuse inside the unit or the thermal cutout on the mag tube isn't closing again after overheating, or possibly the triac or main power relay

There could be a main fuse inside the unit. Mine has one that is ceramic, sort of like the old glass car fuses but ceramic instead of glass. Digi-Key has all kinds of fuses, www.digikey.com.

you can use any 8 amp fuse of that caliber even a bit larger if you had to.

The Daewoo model # is WM 1010CC.
The unit blows a fuse every time I open the door to get food out.
Please suggest a fix!
