Question about Goldstar MW-1420 1200 Watts Microwave Oven

Lightning inside microwave oven

My ~4 yrs old 1000 watt microwave oven has started a nasty habit of acting like an arc welder every 5th time we run the unit (or so). I removed a cardboard cover on the right-hand inside wall to reveal a metal cylinder with holes in the end that seems to have a burn hole in the top. It looks like if I had a new cylinder things might work well. Is it time to throw it in the trash?

Laurabelle Feb 19, 2008

When I turn on the microwave, even for 10 seconds, it starts sparking and smoking. The cardboard cover has a hole in it.

Should I try to fix the problem, or just get rid of this microwave?

My kids think it is great!!!!! I am just waiting for the entire unit to explode.

You better be carefull my friend or you will start glowing in the dark!! LOL Just kidding. But I wont kid about how dangerous that metal cylinder can be with the holes in the top. Thats the magnatron. It has very high voltage going to it and you should never ever touch any wires going to it even if its unplugged as theres a capacitor in there that holds a charge for a time. f the oven is over several years old, Im sure the magnatron will cost more then a new oven, after you add labor and such. It just migfht be time to upgrade to a new microwave?? Good Luck

Clicking noise when going

Sounds like a high voltage arcing. possible transformer or insulation failure causing an overload. Not a recommended consumer fix.

Buzzing sound... Turntable stopped. food heats up but uneven. No microwave fan when heating.. no light inside expensive fix?? Unit is 10 years old

If the microwave oven is 10 years old then it is time to consider a new unit, by your description it is going into cascade failure where different parts have stopped working, the buzzing sound is the magnetron warning you, it is about to fail. The fans job is to keep the magnetron cool while it is running.

Inside is a screen which sometimes arc. These are normally available from the dealers and is not very expensive. Microwaves are dangerous and repairs are better left to trained people.

Microwave Arcing

The metal shelf that comes with most microwave ovens must NEVER come in contact with any surface of the cavity wall or arcing will occur. (this is why its is mounted on plastic clips). IF you are not using the shelf to cook multiple items (as most people don't)....Remove the shelf and store somewhere else until needed.

There is a good possibility that microwave energy is leaking near the magnetron tube, or some other high voltage electrical problem is occurring. I would recommend having it tested by qualified microwave repair technician. A few things you can do....
-Make sure the door seal is clean and no corrosion.
-Check the interior for rust spots or holes and make sure it's clean inside.
