The low temperature alarm flashes the reading with the (!) symbol when the cellar falls below setting 2, which is 50°F from the factory. It clears when the temperature rises above that setting. A setpoint set too low, a cold surrounding space in winter or a unit that keeps cooling past its setpoint can all cause it. Wine Guardian wine cellar cooling unit display · also shown as Low temperature alarm What to do when Flashing temperature with (!) below the low limit shows on the wine cellar cooling unit ### Kind of code Temperature and alarms The controller saw the cellar go past a high or low limit and raised an alarm, sometimes holding the worst reading it logged while the house was empty. The reason can be as small as the cellar door left ajar after a tasting or a long outage, a room gaining heat from new lights or a sunny glass wall, or as serious as cooling that has stopped. Keep the door shut and read a thermometer on a middle rack before touching anything; the alarm is a warning about the collection, not yet a diagnosis. ### Usually leads to Cellar cooling load and room check Measuring the cellar as the cooling unit sees it: insulation, vapor barrier, door, glass and the heat load, to show whether the unit can ever keep up. ### Shows up as Wine Cellar Too Cold A wine cellar too cold feels like stepping into a walk-in: the thermometer sits in the 40s, bottles come out beaded with water, and the unit keeps running long after the room should have been satisfied. ### Make Wine Guardian Wine Guardian systems examined at the cellar, the ductwork and the equipment space when the air stops holding its temperature or its moisture. ### Source Wine Guardian Remote Interface Operation Guide Wine Guardian Remote Interface controller, used with through-the-wall, ducted, ducted split, ductless split and ceiling-mounted units; the Sentinel-series ducted manuals (Dec 2022) list the same alarms. The factory low alarm setting is 50°F. ## Before you book, in this order. Each step comes from Wine Guardian's own guidance for Flashing temperature with (!) below the low limit on its wine cellar cooling units. Follow it to the end: the last card says whether this is a visit. 01 Check the setpoint on the remote and raise it if it was lowered by mistake. 02 If your remote shows a heat symbol, check which mode the unit is in; if it only cools, the room may simply be losing heat to a cold space. 03 If the setpoint is right and the unit keeps cooling anyway, switch it off and book a visit. ### Still there?

Check the setpoint on the remote and raise it if it was lowered by mistake. If it comes back, it needs a visit. ### Is a Wine Guardian low temperature alarm harmful to the wine? A short dip is not a worry. Long stretches well below your usual storage temperature slow aging, so bring the room back up steadily rather than all at once. ### Why does my Wine Guardian cellar get too cold in winter? A cellar next to an unheated space can lose heat faster than it gains it. Some Wine Guardian systems can switch between cooling, heating and auto modes, which helps when the surroundings turn cold. ### Where is the low alarm limit set on a Wine Guardian? In setting 2 on the remote interface. The factory value is 50°F. --- **[Read on the site: Wine Guardian low temperature alarm: the cellar has dropped below its alarm limit](https://winecellarrepair.center/error-codes/wine-guardian-low-temperature-alarm/)** **[Book a visit with WineCellarRepair.center](https://winecellarrepair.center/schedule/)**
