The WS-30 is Sub-Zero’s largest wine storage unit, holding up to 147 standard 750 ml bottles across two independent storage zones. It’s documented only in a Sub-Zero quick-reference sheet captured in 2010 and is no longer produced.
A cooling system cycling far more often than it used to, and a unit that runs constantly without ever settling into a normal cycle, are the issues reported most on a WS-30 — both point toward the door seal working harder than it should. A door seal no longer holding against the cabinet is the other common call, and it’s worth checking first given how large a volume this cabinet has to maintain.
