Rust inside the microwave.

I have several rust areas in the bottom of my microwave oven. It still function fine. I was wondering if it can be sanded and painted, and if it can, what kind of paint should be used. Thank you.

The areas can be sanded and painted, but first make sure there are no holes rusted through. If it's all surface rust, then sand and clean as best as you can. If you have any areas rusted through - get rid of the microwave.
Use the paint sparingly - don't try to cover in one or two coats. Best results are obtained with very, very light coats drying 10 minutes or so (depending on the humidity) in between. 10- 15 coats usually works well.
It's best to do this outside, as you'll have lots of overspray.

As far as the paint - the best I've used for the last 20 years or so comes from A.M.I. Parts. You can find them @ www.amiparts.com or toll free 1-800-522-1264.

There is no problem with rust holes in a microwave if the food is covered.
You can go on using it until it explodes

Can I repaint the rust parts in the bottom of the micro wave oven and what kind of paint can be used?
Hello -

Yes the rusted areas inside a microwave oven can be repainted.

First, you will need appliance paint which is designated for microwave interior use. Check with your local hardware store or local home improvements store to find out what paints they sell which fit the criteria for "microwave cavity paint."

You can read directions for how to go about the project:
https://www.doityourself.com/stry/how-to-repaint-the-inside-of-a-microwave

Read the instructions through, completely, before starting on your project so you know what supplies you need to have available and what steps need to be followed before starting.

Best wishes.

Why is the inside panel of my microwave rusting
There is a significant amount of steam given off during cooking. If your fan is not working or your vents are blocked, the moisture stays inside and hence; rust. You could repaint by doing a bit of sanding and using a tremclad rust paint.

Rust can form from the steam and condensation as you say, and it's a good idea to always cover food and wipe the oven out after using it. You can sand off the bad paint and rust the same way you can on a car, and then touch up the paint if it's a minor amount. Spray paint specifically made for microwave cooking cavities is available. (You don't want to use paint that may have metallic components.) It may be available locally if you have appliance parts stores in your area, and you can find the paint online as well. There's no need to replace the oven just yet, unless you find a good deal on a new one and you're looking for an excuse.

Coating inside oven has de-laminated and rust is forming under coating. Warranty?
Hello spark... no warranty unless the microwave is under 1 year. If there is a lot of rust and delamination you are best off to replace this oven.

The problem with delamination is that it exposes bare metal and can result in dangerous arcing.

If it is not real bad, sand off the rust and spray paint it with microwave cavity spray paint available at this link http://www.appliancezone.com/ShowProduct.aspx?ID=8338&AspxAutoDetectCookieSupport=1

Inside my Daewoo KOR-6Q27 microwave oven, underneath rotating glass plate, white layer (or paint) have piled off and rust have started to emerge. Can this problem be fixed or i have to buy a new one? Was...
I have painted many Microwave oven cavities. You have to sand down the pealed off rusted areas and completely clean and degrease. Before painting, I use laquer thinner as a cleaner degreaser. Fumes can be a bit strong but it has worked well of me. I normally buy an automotive spray paint. They have a lot of different colors and a lot of the import colors can really come close to the color inside the microwave. Spray on thin layers till you get good coverage and make sure you let it dry thoroughly before trying to use. The paint in a Microwave isi not a special microwave energy protective paint. it is only there to make it look pretty and protect the metal. So a good automotive paint normally works fine.

Paint inside microwave oven bottom is peeling
The oven cavity will probably start to rust where the paint is gone. If you're up to it, sand it and paint it with a color that matches the interior color. Other then colors, there is nothing special about paint inside a microwave.

This is often caused by spills and condensation.

The metal will have to be sanded smooth and clean.

You can use a wire brush and naval jelly to get rid of the rust.

If any rust remains, you can use Rust Reformer paint to stop the rust process, then sand it smooth when it's dry.

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

Bottom of door inside badly rusted - oven works fine
Yes you can paint it.. Begin by removing the rust with either a wire brush or a thick paste product called naval jelly. Then prime the area and finally paint it with appliance paint, abailable in a spray can at most hardware stores in the color of your appliance.

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.
