I have a 12 year old Sub zero fridge. It is a 500/550 model, with the freezer
unit on the bottom of the fridge. It has been refurbushed so it basically
works like new. BUT, the one major problem is that water collects on the
bottom of the fridge chamber. I don't believe it is a drain problem, but
rather ice collects on top of the freezer (which is the bottom of the fridge)
and then as the unit cycles, the ice melts and causes water accumulation, mold,
etc....

Any suggestions are much appreciated....
