Sub-Zero wine cooler display · also shown as EC 11 What to do when EC11 shows on the wine cooler ### Kind of code Temperature and alarms The cooler read a zone well away from its setting and raised an alarm, sometimes showing the warmest figure it reached while the house was empty. The reason may be as small as a door left resting on a bottle neck or a long outage, or as serious as cooling that has stopped. Keep the glass door shut and feel a bottle in the middle of the rack before doing anything else; the alarm is a warning about the wine, not a diagnosis. ### Usually leads to Wine cooler thermostat and sensor repair Testing and replacing the thermostat or the temperature sensors that tell a wine cooler when to cool, when the cabinet runs too cold, too warm or back and forth. ### Shows up as Wine Cooler Error Code A wine cooler error code appears as letters and digits on the display, a flashing temperature, dashes where a number should be or a blinking symbol, sometimes with an alarm tone and sometimes while the cabinet stays perfectly cool. ### Make Sub-Zero Sub-Zero wine coolers repaired in place, with the collection kept closed and dark until the visit. ### Source Sub-Zero answer: Classic wine storage (BW) error code EC 11 Classic (formerly Built-In, BW) wine storage.

Confirm the setting on the upper zone has not been lowered by mistake. If it comes back, it needs a visit. ### Can EC11 damage my wine? Wine that gets too cold can throw crystals or push a cork out as it expands. Short dips are rarely a problem, but a section that stays cold needs attention. ### Why does Sub-Zero describe EC11 differently on two pages? Its Classic BW page calls EC11 a cold alarm for the upper section, while its UW undercounter page calls it a warm alarm. We go by the series on your rating plate and what a thermometer shows. ### What usually causes a cold alarm on a Sub-Zero wine unit? Common causes are a probe that reads warmer than the real air, a control that keeps the compressor on, or a zone setting changed by accident. The visit sorts out which one it is. --- **[Read on the site: Sub-Zero EC11: the upper wine section is too cold](https://winecoolerrepair.center/error-codes/sub-zero-ec11/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
