The remote sends and receives data through the control board; when that link breaks, it shows dashes instead of temperature and humidity. On a wireless remote the device may be out of range. On a wired one, the board powers the remote through the cable at about 7 volts DC, so a loose plug, a damaged cable or a missing transformer supply can all bring on the dashes.

- -. ### Can I clear - - - myself? If the remote is wireless, move it closer to the unit or connect it with the supplied cable. If it comes back, it needs a visit. ### Is my Wine Guardian still cooling if the remote shows dashes? Possibly. The dashes only mean the remote has no data; check whether air is moving from the unit and whether the room feels cool. ### Do I need batteries in a wired Wine Guardian remote? No. A wired remote draws its power through the cable from the board, so batteries are not required. ### Can a settings change cause dashes on a Wine Guardian? Yes. If setting 30 tells the remote to read only a remote sensor that is missing, it can show dashes even with a good cable. --- **[Read on the site: Wine Guardian dashes on the remote: no contact with the control board](https://winecellarrepair.center/error-codes/wine-guardian-dashes/)** **[Book a visit with WineCellarRepair.center](https://winecellarrepair.center/schedule/)**
