I've just taken delivery of an ex-display Siemens fridge/freezer from Comet Clearance, that I bought for a very good price. Unfortunately as well as the missing water kit and the expected scratches and dents to the outside, there are two cracks to the inside of the freezer. Both run the full width of the freezer, one is just a hairline crack, but the other is 2mm wide. What I was wondering, does this mean that it is totally unusable, or can I try and seal it with some caulk, or something?

All advice very much appreciated.

This is a duplicate thread as I posted this in the wrong forum. I hope I've got it right now.
