A fault of too much cleaning.

On the inside of the door there is a plastic piece that goes completely around the glass. Take a small screw driver or pick and carefully slide the tool in beside it and once again carefully remove this trim piece by pulling it from it's seat. This will give you access to the screws which hold the handle.

Hi,

To clean between you need to remove one of the pieces of glass...usually the inside is the best....

There are a few screws on the inside of the door theat hold the frame, which holds the inside glass...

remove the frame and carefully remove the inside glass... clean the inside of the outside glass, then clean the inside of the inside glass and then reinstall the froame over the inside glass...

Now you have a clean ove glass again...

Hi Bonnie,

Do not use the microwave with the exposed metal surface.

What you can do is pick up some appliance touch up paint, it comes in a small plastic bottle with a brush. It looks similar to fingernail polish. It should be available at an appliance store such as Sears, Lowes, Home Depot etc.

Clean the area good and use sandpaper or steel wool if needed to make sure the area is smooth and clean. Then use the touch up paint to recoat the surface. Let dry before using the microwave oven, usually a couple hours or so.

No the wave guide is usually a porous material that almost looks like a light colored cardboard piece. Sound as if the stirrer plate is waht you are seeing. Make sure M/W is clean inside completly. Any build up of grease can cause this. Also make sure to check for chipped areas and if there are use an appliance touch up to cover the bare metal areas. A good cleaning will usually take care of the arcing tho.

Actually if you can use a screwdriver you can fix this problem yourself. The glass can be accessed by taking off the screws holding the inside panel to the door on. The screws are visible. Once this panel is off you will see the screws that hold the plate glass in. Keep in mind that the gasket that goes around the glass and inside the door panel are there to keep microwaves from escaping. So in all this be sure to put it back in place right. I have fixed many doors and there really is nothing to mess up. Just put it back together the same way you took it off but in reverse of course. As far as cleaning the glass there is a product call Goof Off that comes in a spray. They sell it at Lowes or Home Depot either one. Use steel wool that you can get there as well and spray a generous amount on the steel wool until it drips slightly and not on the glass directly. Clean all the areas and kinda of use a dry rag to wipe off any excess. After you've taken care of the rust stains and are satisfied take a good glass cleaner like Windex and clean it like regular glass. Keep in mind that the whole door will come off and completely apart to get to both glasses and in between. I would comment additionally that what is in between the glass may be that way due to a leak through the gasket around between the inside and outside glass. However, inspect the gasket well and if you need to you can find a replacement through the dealer or manufacturer of that brand. Keep in mind also that leakage from the microwave door in any way could hurt someone with a heart pacemaker if they get close or someone else that has a battery in it such as people with embedded health units for muscles spasms after back surgeries and the like. Those are the most critical health issues to consider and to be sure that your gaskets are good.
