U-Line wine cooler display · also shown as Temp Lo 12H+, L Temp Lo 6H+, R Temp Lo 6H+ What to do when Temp Lo 6H+ 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 U-Line U-Line wine cooler repair for undercounter cabinets that leak, frost up or stop holding a steady temperature. ### Source U-Line 3036WCWC User Guide & Service Manual (3000 Series) U-Line 3000 Series with the text display, such as the 3036WCWC 36-inch dual-zone wine unit.

Check the zone setting and confirm it was not lowered by mistake. If it comes back, it needs a visit. ### Why would a U-Line wine zone get 10 degrees too cold? Usually because cooling does not switch off when it should, often a control relay. A zone sensor reading warm can cause the same thing. ### Can the cold hurt my bottles? A zone set to 55°F running at 45°F slows aging rather than harming wine. Much colder than that risks pushed corks, so move bottles if it keeps dropping. ### Is Temp Lo 12H+ more serious than 6H+? It is the same condition lasting longer. Both mean the zone has not come back up on its own. --- **[Read on the site: U-Line Temp Lo 6H+: a wine zone is running too cold](https://winecoolerrepair.center/error-codes/u-line-temp-lo-6h/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
