The 424 is an undercounter wine storage unit from Sub-Zero’s 400 Series with dual independent temperature zones, roller-assembly shelves faced in natural cherry wood, and a lighted electronic control panel. It’s discontinued, also printed as the 424/O.
Both zones drifting together over a matter of days is the issue reported most on a 424, which points toward the door seal rather than either zone’s individual sensor. A door seal no longer holding against the cabinet, and interior lighting that doesn’t come on with the door, are the other common calls on this model.
