What happens when you over heat the oven.

 This is a photo of what happens when you over heat the oven.  The customer stated that the stove they were using had a leak and was burning at the side instead of the top. This is what melted the oven, the direct heat from the stove flame onto the aluminum sides.
As you can see the oven got so hot it melted the bottom section.
Although I think you could still use this oven if you had to. I made this
person a new center section for $15.00 plus shipping.

So make sure to be careful with your stove so that it is not heating directly onto the sides of the oven. It should be centered in the bottom of the oven under the diffuser plate.
