Gelato Ice Cream Freezer Cart - $100 (West Bloomfield)

We have a nice Gelato Ice Cream Freezer Cart that we've been using, and it has been working great up until last week.
when it just stopped freezing, I guess it needs freon or has a small leak, but not sure; I am selling it as is.
Plugs into a 110 outlet.
Feel free to fix it or use it for parts; comes with the lock and key.
Approximate size.
