What - - -
actually means.
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.

What to do when - - - shows on the wine cellar cooling unitKind of codePower and controller
The unit saw its supply dip, surge or drop out, or the controller has lost contact with the board it drives. The cause is as often a shared circuit, a tripped GFCI outlet, a loose connection or a storm outage as the unit itself. A breaker that will not stay on or a scorched smell means switching the circuit off at the panel, standing dry and away from the unit, and keeping the cellar door closed until the technician arrives.

What not to do
Dashes do not tell you whether the unit is cooling; it may be running normally behind a remote that cannot report it. A remote that can open its settings but still shows dashes is often set (setting 30) to read a remote sensor it cannot find.
