That sheet is called the Waveguide Cover and its function is to stop debris and food entering the aerial and magnetron.
Replacement is essential and must be made of mica.
It can be purchased from a dealer at a reasonable cost.
Google the manufacturer and find a dealer.
Hope that helps.

I get an occasional spark when microwave is in use


Presuming that you have iliminated the possibility of any metal objects that are not meant to be in the machine being in there (and this includes dishes and other items with silver or gold leaf on them, which WILL spark and burn!) then take a look inside the oven its self. You will find a waveguide cover. It is usually a strange flakey silvery plastic/card like material called Mica and is usually on the same side of the microwave wall as the control panel (So if the picture on this thread is accurate, I will guess the Mica cover is on the right hand wall inside as you look at the machine from the front) . Over time, the magnatron (the thing that creates the microwave energy) will often burn a hole through the mika, or cause a dark brown or black burn mark in it. If this cover is even slightly damaged then it may well cause sparking inside the machine. These covers are designed to be removed and you can buy replacements for them from electrical stores.

What is the mica cover?


Hi, a mica cover is inside the oven cavity, usually on the right hand side or in the roof you will usually see a small cover that looks like it is made of cardboard. It is often held in by one or more screws. It is called the waveguide cover. It is usually made of a material called Mica. Its purpose is to cover the aperture through which the microwaves enter the oven cavity from where they are produced by the Magnetron behind the control panel. It stops moisture and food particles getting into the "workings" of the microwave.

My Microwave is arcing due to its demaged Mica sheet. Can I replace it with any other ordinary Mica sheet cut to its original size & fit in its place? Will it work? Or are there special Mica sheets...


Hello.

Yes you can buy mica sheets made for microwaves at appliance repair/parts shops.Scissors work well for this. A razor knife might be needed for notches etc. If so, several shallow cuts work better than trying for one deep one, as your not as apt to slip. I usually put the leftover material in a plastic bag and tape it to the bottom of the unit so I could find it the next time.

Hope this helps you.

What is watts for goldstar MA 1280M Microwave and if it is over 1100 watts cani i adjust it down


You can set it to different levels. It is doubtfull the magnetron will deliver more than 750 Watts as that is about all they can produce singley. Commercial ovens use at least two magnetrons.
Most specs on microwave ovens quote the power drawn not power produced.
I hope that helps.

I was cleaning inside the microwave and a rectangular part on the inside came off the right hand wall. I cleaned it further and tore it. Is this needed in the microwave, can I get a replacement?


That piece is called the waveguide cover. It's a mica sheet that goes over the hole in the side of the oven where the microwaves enter the cooking cavity. While the oven can work without it, you should replace it. It's meant to keep food particles and dirt from getting into the area of the microwave antenna, where it can possibly lead to damage.

I gather from researching the part that yours is a UK model oven. Here is a source for the replacement waveguide cover. If you're in some other part of the world, at least you'll know what you're looking for when you search for a more convenient source. You may be able to find a replacement locally, as the waveguide cover is a commonly-replaced item. Check with appliance parts houses or service shops in your area to see if one might be available.

I need a microwave guide cover for model mw8115ss


Buy a sheet of mica. It's cheap and easy to work with. Draw and cut a new cover from a sheet and replace the damaged one. There's a example of how cheap mica is (I just used a sheet like that today on my Miele microwave).

Don't try punching holes in mica, always drill them gently. It will easily flake.
