Summary: Top broiler won't stay lit. Goes off after a pan is placed into the oven. Seems like it senses overheating. Called Kitchenaid and they wouldn't help. They just wanted to sell me a service contract. After 18 months the top oven died completely. Called for service and they replaced and ignitor. That fixed the bake but not the broil so they replaced the top ignitor and ordered a new gas valve (still waiting).
Summary: The "stainless steel" finish isn't really stainless steel. It is so delicate it is scratched by a fingernail or even a paper towel. Right now, I have some tomato sauce on mine that may never come off without scratching and it is a new range. If you need it converted from natural gas to propane, pay someone to do it. My husband is an internationally known expert in combustion systems and it took him two days.
