In most wall ovens, the important anatomy is at the top - the electronics. The wiring that connects the controls to the elements in each oven is housed inside the case. I can't imagine how a dent in the outside flange could affect anything other than how the oven fits into your cabinet.

That having been said, look up the installation instructions and wiring diagrams for your model and double check. If there's nothing important in the dented area, you'll be fine.

That dent likely will not pose any problem. Once you do get it installed, you should fully test out the features of the oven, including the self clean to make sure all is good. You might try to negotiate a bit of a refund due to the dent, but since it is a floor model they may not be willing to do so.

Thanks for responding. Makes sense that the dented frame shouldn't be an issue.
