Used chest freezer not cooling
One of two situations has occured with your used freezer:
1: The unit freon needs to be recharged, this happens when you develope a leak in the freon coils, or the unit is old enough that the freon has reached it's usable potential.
2: The compressor may seem to run fine, but in fact, has an internal problem.
My suggestion, return the unit if you can, and walk the isles of your local Menards, Sears, or any other local vendor in your area, and see how much prices have declined for the chest freezer.
The initial investment for a new freezer will offset any problems you might have with any other used unit, and the warranty is always a plus if you do have problems with the new unit.
