What to do with a 32 year old refrigerator?

[monocoque]

I'm in the process of a driveway shell-off to replace the frame on my Ambassador. Frame Rot So far have I removed the refrigerator, along with about half the interior, and now the refrigerator is sitting on the driveway. So now I have a question: What does one do with a 32 year old refrigerator? It's a Royal Dometic, gas/electric, automatic defrost, model rm100. I have no idea whether it works or not. Although some of the knobs have either broken off or fallen out of position. Plug it in and see what happens?
