600-series built-ins, it integrated columns, pro 48, and 400/700-series wine columns make up most of the Sub-Zero install base in Switzerland and the CR-210 corridor. The kitchens we touch here are estate-construction kitchens with full Sub-Zero and Wolf suites, which shapes both the diagnostic profile and the parts inventory we route to St. Johns.
Most Sub-Zero calls in St. Johns are defrost-circuit and damper-assembly work, plus condenser-coil service. Second-most-common is wine column dual-zone drift and humidity-sensor replacement. Both have common parts on the van, so first-visit close-out is the norm.
Routed as a half-day block because of distance. We document every service with model and serial plate photos, part traceability tags, and an install-completion photo — same packet to the homeowner and the warranty file.
