I am not new but new back to reborning .. I just ruined my Isaac head with my nuwave oven Beware!

I forgot to put the extender ring back on my nuwave oven… BEBE I am guessing it was to close to the top … not sure what caused the tire track looking marks but there was no popping it back out.
I was cooking dinner and not feeling well …I have only had the nuwave oven a month or so but i doubt i will ever do that again .

Sorry to hear it. it’s so easy for it to happen and so devastating when it does.

Thank you bebe.
