I have had my Kenmore slide-in 3-4 weeks now -- tonight it went crazy!

I was baking baked potatoes in the oven and not even using the cooktop -- all of sudden it starts beeping with error code E0 36. The only way to get it to stop was to flip the circuit. Next it was error code 39, then error code 21. Every time you hit Stop, it was stop but then start beeping with error code 21 again.

I called and spoke to a tech (just like the manual says to) and he was really of no help and could not even tell me what error code 21 means.

The stove eventually stopped displaying the error code. Now I notice that the cooling fan is running and the oven hasn't been used in six hours!

Ugh! How disappointing! I know it is under warranty but I hate the thought that there is already something wrong with it.

Service is coming Tuesday am.
