The BW-30 is a 30″ Classic column wine storage unit, published in both stainless and panel-ready overlay forms, also printed as the BW-30/O. It’s from Sub-Zero’s discontinued Classic wine generation, with its product page archived rather than current.
Both zones drifting together over a matter of days is the issue reported most on a BW-30, which points toward the door seal rather than either zone individually. Interior lighting that doesn’t come on with the door, and one storage zone running warmer or cooler than it’s set to, are the other common calls.
