Rust in the Microwave and the surface is peeling away

I was wondering if this condition is dangerous to the food

Anon - Good question. Here's an answer I found on the site howeverythingworks.org.

As long as the oven's metal bottom is sound underneath the rust, there isn't a problem. The cooking chamber walls are so thick and highly conducting that they reflect the microwaves extremely well even when they have a little rust on them. However, if the metal is so rusted that it loses most of its conductivity in the rust sites, you'll get local heating across the rusty patches and eventually leakage of microwaves. If you're really concerned that there may be trouble, run the microwave oven empty for about 20 seconds and then (carefully!) touch the rusty spots. If they aren't hot, then the metal underneath is doing its job just fine.

You might want to consider getting a new one. They have really come down in price in recent years. Thanks for your question. Pat
