In St. Johns the Sub-Zero wine storage install base runs heavily on 424 / 427 / 430 / 715TC / IW-30. Our work here is dual-zone thermistor verification, humidity-sensor service, and LED-column work — finished on the first visit when the model is confirmed at booking. Most-common call: upper-zone drift on the 424/427 — almost always thermistor or damper, never the board. Service routes through Switzerland and CR-210 estate construction touch this combination often enough that the common parts ride the van by default.
