I bought a 6.9 cubic foot Magic Chef today. I had to borrow my neighbor's truck since I don't have one myself. I noticed after I got it home and out of the box that the outside upper left hand side had a small, light dent. Initially I thought it wasn't a big deal since it seemed cosmetic only, but then i read the warning labels on the box about the coolant tubing. Without any prior experience owning a chest freezer, how big of a deal is a light dent on the exterior? Will it impact the freezer's performance. Thanks for your advice.
