On a dual-zone cabinet the compressor and condenser are shared and the sensing, the fan and the damper for each zone are not — so one correct zone rules out half the appliance immediately. ### Right matters more than cold A wine cellar is judged on stability rather than on temperature. Displays show a number and not a trend, so a cabinet that swings four degrees through the day looks perfect every time anybody glances at it. A thermometer in a glass of water, read morning and evening, is the honest test. ### The one place this make contradicts itself The E-numbers on undercounter refrigeration and on dual-zone wine cabinets do not carry the same meanings — the manufacturer prints two different tables. It is the single most confusing thing in this archive and it is the reason the model number is asked for first. This article is based on: - Official manufacturer documentation - Internal repair procedures - Technician repair history - Company quality standards Before you book ## Questions about viking wine cellar temperature wrong or swinging For wine, yes. A cabinet holding steady at 58°F is doing better by the bottles than one oscillating between 52 and 62, and the display on most equipment makes that hard to see. Then the model number matters, because this maker publishes different meanings for E1 across its cabinets. Give us the number and we can tell you which table your cellar uses rather than guessing. Useful, and it narrows things immediately. The compressor and condenser are shared between zones; the sensing, the fan and the damper for that zone are not. It is usually a contained repair.
