Hello Aloha girl.

If burner caps are discoloring or blackening after each use, a flame adjustment may be needed. Too much air mix can cause soot and a yellow flame. Call your gas company or your gas installer to resolve.

Please note that due to their continual exposure to high temperatures and abrasion by the cookware, it is normal for the grates will gradually lose their shine.

Thank you for checking.

Hello - this is Nancy at GE and I am happy to help you.

The self-clean cycle saves time, money, and energy. The oven is cleaned by heat, at temperatures above normal cooking temperatures, which causes soil to disappear from the oven. A device in the oven, called a smoke-eliminator, further converts soil into an essentially odorless colorless vapor. A slight odor may be detected the first few times the oven is cleaned.

I hope this helps! Thank you for contacting GE!
