It will have to be sanded smooth and clean and dried thoroughly.

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

My microwave is about 7 years old and has recently started sparking when I heat things in it. Can it be saved or is it best to buy a new one?


sparking usually relates to i) using metal in the cavity or ii) some burnt food on the roof iii) the waveguide cover 'mica' panel is burning iv) door area enamel has been damaged. After 7 years you may want to bin it and get a new one as they are now so cheap, fixing them is usually more expensive.

When i turn the microwave on it has electrical short it is like there is something metal inside and everything still works what causes the electical flash


The interior of the microwave is insulated with an industrial white enamel paint to prevent the magnetron from arcing on the inside, some of the enamel has worn off exposing metal,or the magnetron is shorting, either way this is very unsafe to use and should be checked quickly, and left unplugged in the process.

The problem is that the magnetron is arcing when it is running and it has found a couple bare spots 'exposing the metal'. The microwave uses a special industrial white enamel paint to prevent arcing, it is very important that the oven be removed from service until the situation is rectified otherwise there is a danger of shorting out the magnetron.

There is not any power in the door itself. However if the chassis has chipped paint or corrosion the RF from the microwaves magnetron will cause those bare metal areas to reflect the concentrated RF energy and cause sparking.

The only Whirlpool Microwaves that have been recalled, has a model number beginning with XC and had a green sticker on the bottom face area of the chassis where the door closed.

I have often been able to clean and paint the bare metal areas with the correct paint to stop the RF reflection sparks. Using the model number above it is white enamel "appliance paint" that you would use to paint the bare metal areas. A word to the wise.... do not sand outside the area to be painted. Otherwise you re-introduce your current problem post repair.

The model number you passed is missing the very last digit that would be from 0 to 7 (Eight models)

Thanks for choosing FixYa,

Microwave safety after repainting


Too generic...Did you use the high-temp appliance enamel recommended, or a spray...or worse?

Was the rust inside where it can contact food through the circulating air, or on the outer body?

First thought based on how I read the question: Never use that machine again...but that's based on the word "in" instead of "on my microwave".

If the rust was around the door frame, outside the seals, and you used an enamel (of course) then you may be OK...but...
Considering the fact that a cheap microwave is a drop in the bucket when compared to your family's health...Why risk it?
