SubZero sweating on rear of cabinet

I have a Subzero bottom freezer refrigerator that is sweating on the rear of the cabinet behind the freezer section. The sweating does not occur between the doors but there is also some sweating on the one section of the freezer door. Can this be repaired?

Larry,
Which model do you have? 611 or 650? How old is it?
Describe exactly where it is sweating. On the outside of the cabinet shell on the back? If so, first remove the back cover and check to make sure the refer drain hose has not split. This hose runs down to the drain pan. Verify the ice maker water line hasn't split. Also check behind the refer crisper drawer to make sure the drain tube is intact from the drain trough. If all is well, then you may have a foam void. If this is a newer cabinet, I would talk to the vendor about a replacement unit.
If you feel inclined, pull the freezer drawer out and flip it upside- down. Remove the trim in it's a frame or overlay unit. There are holes on the bottom... one is the hole to charge the door with the foam mixture(an A and B part, that mixes inside the wand) and should have two .108" holes as air bleeders. On the side with the sweating issue, push a wire into the hole. You will know right away if there are voids.
Where sweating is an issue, press with your hand on the surface with moderate pressure, it will not give more than a 1/16 to 1/8" inch if there is foam there.
Let me know the results, Brian
