Question about Microwave Ovens

10 Answers

Have a new GE microwave. It has a metal rack. I put in a container that was too high. It must have knocked the rack off its plastic holders, allowing the metal rack to touch the back and side inner walls of tje oven. It arced, causing light scorching and two pits where the rack corners touched the inner walls. They do not go right through the walls, although I can see the metal where the acrylic paint was cinged off..As a matter of opinion only, is this microwave still safe to use?

    Is the oven still safe to use with these two new little pits ( that dont go all the way through the metal casing) in the microwave walls caused by the arcing?

  • sdrawn Feb 06, 2009

    The arcing was caused simply from metal rack touching the sides. My main concern is the two little
    pits in the walls caused by the sparking. these pits do not go right through the microwave walls but i am concerned about radiation still. do you think these pits (dents) caused by the arcing will allow
    too much radiation to leak out to be safe. thats my question to clarify

I will not suggest to use it in such a way as its very risky and the results will be very dangerous and fatal.just call a techniciasn at your place get it checked and adjusted properly.it will cost you some dollars but will be very much helpful till the machine lasts.

As for the usage of microwave its very risky and dangerous.but for safety purpose i can say many users use their microwave as you r using but they cover the metallic objects with a wooden particles and also stand on a wooden table as this will make the place curren free if it gets short any day.due to wooden fittings it will never give the current outside.

Welcome to Fixya! You can Recoat the rack with Porcelain Repair Kit and it will cover the Metal just Fine. Also, If the Pits do not go all the Way through, Then it should be OK. Definately Cover the Metal on that Rack though. The Porcelain Repair Kit can be Purchased at Lowes, Home Depot, Or Wal-Mart. Please Rate My Response! Thanks!

Yes it is safe. The plastic is there to insulate the rack - as you stated.

Pry off plastic tab. Clean up burn marks with sand paper and touchup paint. Order a new rack clip. Also clean any burn residue off rack.
MOST IMPORTANT: After the repair, do not put the rack back in unless you are cooking on it. Running the microwave with nothing on the rack is what causes this to happen.

Put A foil pan in it to warm and now has a burning smell and makes a noise, not heating. assume we blew something Sharp R-7A85


Never, never, never, never, never put anything metal in a microwave oven! No metal, no pot or pan, no silverware, no plate with metal trim ... nothing! No "Jiffy Pop" (comes in a metal container). Use ONLY microwave safe containers. Some claim there are health concerns (dangers) to using anything plastic in a microwave. The claim is the chemicals in the plastic which were not meant to be consumed are consumed as they are burned out of the plastic into the food. These chemicals are know to some to be cancer causing. I am not making this claim ... only passing on what I have heard about plastics. For myself, I don't use plastic or paper (fire hazard) in the microwave. For one thing, I don't like the taste of food that has been prepared or reheated in a microwave in a plastic container - particularly coffee.

Having said that ... here is what is going on. You probably reflected microwave back into the magnatron and ... well ... cooked it. In my area, such damage is not economically repairable. The tech wants $100.00 to look at it, magnatrons are typically $50 to $100 or more. There could also be other damaged parts ... repair bill could be more than a replacement oven.

If you find a oven that comes with a rack, here is how that works. You will observe that the rack sits with flat feet on a carousel which is typically out of the range of the microwave OR has been built to reflect the waves in a manner that they will not damage the magnatron. Typically, a rack will be made of very small round stock that will not reflect much in any single direction ... besides that, you would have food on the rack that would absorbe most of the energy anyway.

If you replace this oven, please ensure you review all the warnings and instructions that will accompaly your new oven ... even the seemingly silly stuff like "dont use the microwave in your bath tub to heat the water".

I believe your oven is cooked. I'm sorry you are having this trouble and I hope my comments have helped you to arrive at a workable solution to your problem.

Sparks coming from inside of oven


This is a simple fix.

You need to remove the rack and all of the holders.

Clean the metal thoroughly where the rack mounts fit.

Replace all the rack mounts with new ones, insert the rack and you're all set.

Then be sure to keep it really clean, even if you have to remove the rack and new mounts periodically to get it really clean.

My microwave sparks inside where the metal rack rest on the plastic holder


You will need to remove the rack and all the rack holders.

Any grease or carbon arcs will have to be cleaned thoroughly, and if the metal is charred or damaged, you will need to apply some high-temperature appliance paint, available from places like Wal-Mart or Lowe's.

Then replace all of the rack supports, not just the one that arced.

My microwave is making a weird noise and also a flash of light is coming off.


If yours has a metal rack, it may be arcing at the rack holders.

If so, you will need to remove the rack and all the rack holders.

Any grease or carbon arcs will have to be cleaned thoroughly, and if the metal is charred or damaged, you will need to apply some high-temperature appliance paint, available from places like Wal-Mart or Lowe's.

Then replace all of the rack supports, not just the one that arced.

Another common cause of
such noise and flash is grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.

The waveguide cover is usually about the size of a playing card and often held in place by a plastic rivet.

It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!

Sometimes it is a circular piece in the ceiling of the oven.

The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.

If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart or Lowe's.

If your waveguide cover is burned, it will need to be replaced.

Caught fire


>Should a microwave be obsolete after 5 years?

Not at all. You can just order a new rack support (or a whole set of them).

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

Quite often this arcing is due to grease or food particles stuck between the holder and the hole it goes into, etc.

Burnt hole in microwave


Is the hole actually bigger than it originally was or is it just empty because the rack support got burned up & discarded?

The rack supports / rack holders can be ordered. The part number is WB06X10140 (or WB6X10140) and they're less than $5.00 each. You can find them in stock here.

If you install a new rack support in the hole, then any gap or hole around it can allow grease to accumulate, and that can lead to arcing. But you can seal it safely & easily.

Once the support is installed and everything is squeaky clean and dry, you can apply a small amount of silicone caulk into the gap or hole.

Let it dry it overnight with the door open, then use a razor blade or X-acto knife to gently trim away any excess caulk.

That would be a really good fix.
