Has anyone recently rebuilt or replaced their refrigerator? I currently have a top loading ice box with a cold plate. It appears that a previous owner attempted to insulate the ice box by adding insulation to the interior. I now have corner seams filled with caulk that leak and no apparent drain (yuck). I've thought about manufacturing a stainless steel or molded plastic box surrounded with foam insul. and keeping the cold plate. Any suggestions on replacing or rebuilding this unit?
