I am just wondering if anyone can offer some guidance or good websites to look at. The hole is about 18" wide by 22" high
You may still need a vent because the refrigerator
needs to reject heat somewhere. Remeber a refrigerator
works by taking heat out of one space and putting it into another. Without a vent at the back, there is no place for the heat to go. If you decide on no vent then the way to repair a big whole is either get a piece of a wrecked boler
. or use fiberglass cloth and resin to attach a piece of plywood on the inside of the hole. Then coat the wood with resin. Then a thin layer bondo so that you still have a cavity for the gel coat. Then gel coat to match and bring the hole up flush with the outside.
You can also do the repair backwards by clamping/taping something firm and flexible on the outside covered in the right kind of plastic, then gel coating directly onto the inside of the plastic, then skipping the wood and going directly to a couple layers of fiberglass cloth. I filled up the holes for my furnace
using this method, but the whole might be a bit large.
