After 15 years or so of forcing the oven door closed around a large pizza box, my oven racks no longer support items with any weight. they collapse. At first I thought the racks were warped, but that does not appear to be the case. Rather the oven sides have pushed in a bit, enough that the racks barely rest on the built-in rails.

I think the replacement panels are unavailable due to the age.

Any other way I can fix this?

Another issue is the lower oven often won't come on. Starts for a few seconds and then shuts off again. Usually if we keep trying we can eventually get it to stay on.

New ovens are so expensive I'd rather not go that route if I don't need it.
