A cellar that is too dry lets corks shrink and wine seep; one that is too damp grows mold on labels, racks and drywall. The cooling unit sits at the center of both, because every hour its coil runs cold it removes water from the air. A unit that is oversized for the room, or set with a narrow differential, runs short, cold cycles and dries the cellar out; a unit that is undersized, or a room with leaks in its vapor barrier, keeps pulling in moist air that the coil never fully removes. Many systems carry a humidifier module or a separate humidifier, which has its own water supply, valve, pad or nozzle and a humidity probe, and those clog with scale and stick. The technician measures the humidity at several places, compares it with the controller's reading, tests the humidity probe and the humidifier, and looks at the fan mode, which on some controllers changes how much water the coil holds back. Where the room is the cause, you get a plain account of which walls, ceiling or door let damp air in, and what would stop it. How the visit goes ### What it usually costs Low to moderate · Humidifier module, humidity probe or settings Cleaning a scaled pad, freeing a valve or changing fan and differential settings is low on the scale. A new humidifier module or a separate humidifier with its water line is a step up. ### Answers 6 problems Wine Cellar Humidity Too Low Wine Cellar Humidity Too High or Mold · Condensation on Wine Cellar Walls or Glass · Cellar Cooling Unit Short Cycling · Cellar Cooling Unit Leaking Water · Wine Cellar Too Cold ### Comes up most on Ducted cellar cooling unit Split-system cellar cooling · Through-the-wall cellar cooling unit · Ceiling-mounted cellar cooling ### Codes that lead here EA · EA · !2 · Flashing humidity with (!)

Leave the cellar settling toward its window, and tell you what to watch on a hygrometer over the next week. 01 Measure humidity at the unit, in the middle of the room and near the door, and compare them with the controller's reading. 02 Check the humidity probe, the humidifier module or unit, its water supply, valve and pad, and the drain. 03 Review the fan mode, the set point and the differential, which change how much moisture the coil removes. 04 Repair or replace the humidifier part or the probe, correct the settings, and note any gap in the room's vapor barrier. 05 Leave the cellar settling toward its window, and tell you what to watch on a hygrometer over the next week. ## The problems it answers. 6 of them, from wine cellar humidity too low to wine cellar too cold.

Most cellars aim for somewhere around 50 to 70 percent, with 60 as a common target. A few points of drift is normal. Long stretches below 50 or above 70 are what to fix. ### Why is my cellar so dry when the cooling unit works fine? A unit that is larger than the room needs, or that cycles often, removes water on every short cycle and dries the air. A room that takes in dry winter air through a door gap does the same. The fix may be a setting, a humidifier or a better seal. ### There is mold on my wine labels. Is the cooling unit to blame? It can be, if it is too small to keep up or its drain overflows into the room. Often, though, damp air is getting in through a gap in the vapor barrier or a door that does not seal. Wipe the mold, keep the door shut and book a visit that checks both. --- **[Read on the site: Cellar Humidity Control Repair | WineCellarRepair.center](https://winecellarrepair.center/services/cellar-humidity-control-repair/)** **[Book a visit with WineCellarRepair.center](https://winecellarrepair.center/schedule/)**
