Wine Guardian wine cellar cooling unit display · also shown as High humidity alarm What to do when Flashing humidity with (!) shows on the wine cellar cooling unit ### Kind of code Humidity The unit or its hygrometer reads the cellar's air as too dry for the corks or too damp for the labels and the walls. Cooling pulls water out of the air, so a unit that runs long in a leaky room tends to dry it out, while a gap in the vapor barrier, damp ground or a clogged drain can push it the other way. A humidifier or humidity kit, where one is fitted, is checked along with the door seal and the room before a sensor is blamed. ### Usually leads to Cellar humidity control repair Bringing a wine cellar back into its humidity window, roughly 50 to 70 percent, by fixing the humidifier, the fan settings, the drain or the room. ### Shows up as Wine Cellar Humidity Too High or Mold Wine cellar mold starts as a musty smell, then white or green fuzz on the rack posts, spotted labels and dark specks in the corners, usually with a hygrometer reading well above 70 %. ### 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. ## Before you book, in this order.

Check the door seal and any openings into the cellar, since a leak lets in moist air. If it comes back, it needs a visit. ### Can a Wine Guardian lower humidity by itself? The unit dries the air while it cools, but it has no separate dehumidify mode. If the room stays humid, the moisture source has to be found. ### What humidity should a Wine Guardian cellar hold? Wine Guardian sets its humidifier target at 55% from the factory. Most cellars do well from about 50% to 70%. ### Why does the humidity alarm show after I open the cellar door often? Each opening brings in warmer, wetter air. The reading should settle once the door stays closed and the unit runs a few cycles. --- **[Read on the site: Wine Guardian high humidity alarm: the cellar air is wetter than its limit](https://winecellarrepair.center/error-codes/wine-guardian-high-humidity-alarm/)** **[Book a visit with WineCellarRepair.center](https://winecellarrepair.center/schedule/)**
