Arcing inside and there is now a small hole on the panel side. Is this fixable?

    I have already replaced the wave unit and cleaned the inside of the microwave. It worked several times but then the arcing happened again. Just above the wave unit there is a small burn hole that looks like it may have gone through the lining. Will microwave "paint" or something else actually fix that? Or do I need to replace the whole unit?

  • yvonnejeanmi Jun 20, 2009

    I am still waiting for a reply to my second posting in which I am asking if my microwave, which appears to have a hole burned through the lining on one side, is fixable or if I need to replace the whole unit. Please advise,

Hi,

It looks like there's lightning (arcing) inside my microwave When you see arcing inside your microwave, it's because of food or liquid left in the cavity or on the wave-guide cover:

  • If the wave guide has any burn spots, replace it and clean the unit well.

  • If the cavity has any burn spots, spot-sand it smooth and touch it up with microwave interior paint.

Note… If there are any burn holes in the cavity, don't use the unit-seek help from a qualified appliance repair technician.

Thanks for contacting Fixya

Inside the wave guide cover of a Panasonic Micro is a copper colored nozzle looking device. If the edges of the nozzle are jagged and burnt looking it is best to replace the micro. Panasonic's with inverter technology are prone to early burn out.

Hi,
In my opinion you should replace that microwave oven because that small burned hole can emit micro waves out side oven that is serious danger for life.
Do not take risk and consider this oven a junk.
Thanks.

Why is there a burn hole inside the oven, on the cardboard?


That's actually a mica "window" (cover) for the microwaves to come out. And it sounds like the magnetron started arcing and burned a hole in that cover. Either that, or some food (frequently spaghetti sause) got splattered on it, and the microwaves heated it up so much that it burned a hole in the cover. Does the microwave oven still work (heat)? Do you see or hear any arcing? If the microwave oven still works and there is no arcing, you can just replace that cover. Check SearsPartsDirect.com or RepairClinic.com.

It may be the oil in the popcorn---do you own one of the covers that go inside to cover so food does not splatter?

Sharp R-980A Convection oven - arcing without any metal (except turntable) and smoking inside.


There is a shorted happening when the magnetron release energy. The problem of that is the waveguide already not in focus (already have a big hole on it) hence it scattered the microwave wave elsewhere inside the unit and also to its own metal casing. That cause's to arcing when operating.
Waveguide hole needed to be replace and it need some cleaning & painting of the affected metal (usually near around the magnetron waveguide). Once it's done the unit will not arcing again.
I do hope I answer your problem. Thanks for asking.

This is caused by either carbon arcing from carbonated food deposits or metal dish or bowl being used inside the machine causing a track. Even a recycled paper towel can cause it as the towels have metal traces in them.

Magnetron has 2 small holes in antenna due to previous wave guide being dirty.Is the microwave still safe to use,no sparks or arcing.


Some magnetrons have holes in the antenna by design. If these are clean holes on opposite sides near the RF gasket then they belong there. If the holes are obviously burn damage but don't cause any improper operation, the oven is safe to use.

Metal plate on inside of microwave has hole & is arcing.


The Arcing is a real bad sign, and you see the "Brain" has detected a fault condition, most likely the Power Supply and or magnetron, or High Power Diode, has "Faulted" and it shuts down for Safety reasons. Due to the danger existing inside MW, I recommend that you have it serviced by a qualified person. Always get a firm "Quote" before proceeding with any work. Be careful, as often a repair may cost as much as a new one.

Paint damaged in side microwave oven


1) How is the cavity damaged? Is it just peeling paint, or is it rust? If it's rust then the microwave could be dangerous.

2) The antenna cap usually has a small hole in the centre, but if there are any other holes in it the magnetron itself could be damaged, and holes caused by the magnetrin arcing.

Sparks in oven


the burning is normally caused by a small particle of food getting stuck on the waveguide cover, this then carbonises and starts to arc. replacing cover should return oven to normal
