Yes, take the rack out and recycle it. I do not know why these micro-wave
company put racks in the micro wave ovens. You get some insulation on the inside
the micro flaking off next the rack.
The mega-tron tube is a very high energy transmitter. The energy will come
out of the top inside the micro wave oven in a wave guide. Micro wave energy
that generation by the tube is high frequency into Gega Hertz. You have a metal
tray in side the micro wave acts like a big capacitor it stores energy in form
of heat the next you know it look like Marconi is putting on a lighting
display.
Leave the wire tie on a loft of bread and put in you micro wave oven to
defrost. The next thing you might see is a load bread burning, instant toast.
----The use of micro wave were invented by the British before WWII. The mega
tron tube generation very high frequency radio wave and these wave struck an
object 100 miles away some of this beam energy would balance back to a
receiver-----You have Radar.... I wish you and your family well being and be
careful of micro wave ovens it can burn from inside out. GB you...stewbison
How old is your m wave? Sounds like you need to replace it .You can get a new one from Wal mart for under 75.00.and that will get you the big 1 sq.ft one..I once broke the plate in my m/wave and believe it or not they wanted more for the new plate than I paid for the M/wave BEFORE you do that check your power level settings perhaps it was turned down
YOU SHOULD NOT RUN MICRO WITHOUT ANY THING IN IT / THIS WILL OVER LOAD THE MAG TUBE . AND SOME TIMES FRY IT .. The sparking and arcing is probably a bad wave guide . this is sometimes caused by food splater / it gets in the cracks and corners and then cooks till it truns to carbon which conduts the micro's and thus arching .. clean it good and touch up any burns in the metal and repl wave guide cover. mm hope this will help .. mm
It looks like the metal part inside the oven is exposed to the high frequency rf waves. this may sound strange but try coating the metal part with fresh paint. remember no metal inside the oven will stand the waves created inside the oven the spark u see is the waves hitting the exposed metal part inside the oven
Q - The microwave display counts down and the inside light is on, but nothing is heating and the fan is not running. A - This most commonly is abad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common. Q - My microwave is running and sounds like it is working but will not heat up anything. A - Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay..... Q - The microwave makes a loud "hum or buzz" noise but will not heat up the food? A - 9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section.
Hi There!
Check behind the "Wave Guide Cover" on the inside cavity. There may be moisture or food residue behind it. Should be a cover that is plastic or Mica. Really strange that it's sparking being new. Also check that you use plates without gold or silver trimmings (Crockery or porcelein). This will also cause sparking. Remember that microwaves will always go to the first organic source in its path. The wave guide cover, if soiled, is very close to the tip of the Magnetron and will therefor result in arcing. Good Luck, JUS004
