I have a Sub-Zero Model 511 refrigerator (w/bottom drawer freezer).
Recently there has been ice buildup inside the refrigerator. I have vacuumed the compressor intake filter and the ice disappeared for a few days.
It is almost impossible to pull the entire unit out from it’s cabinet installation. Can you please tell me how to remedy this problem? (See photos)

Have you checked the defrost timer?
