That is a very nice cabinet you built for it. As someone else already said, that is a lot of pretty work to toss in a used freezer. I bought a used one about 15yrs ago and it also died. I would never do that again. My coffin keezer is only a 7cu ft model and yours appears to be larger so I know the cost for new is >$200. But you have more than that tied up in labor in your build.
