What No Comm
actually means.
No Comm means the display on the door and the main control board are no longer communicating. U-Line asks owners to disconnect and reconnect power; if that does not help, its service table points at the display and its data cable, which may mean replacing the whole door.

What to do when No Comm shows on the wine coolerKind of codeControl board and display
The electronics that read the sensors and switch the cooling, the fans and the lights have reported a problem with themselves or lost touch with the display. A loose ribbon cable, moisture that reached the touch strip or a brief power surge is checked before a board is condemned. Boards and displays are usually specific to one model, so the number on the label matters here more than anywhere.

Before you book,
in this order.
Each step comes from U-Line's own guidance for No Comm on its wine coolers. Follow it to the end: the last card says whether this is a visit.
Unplug the unit or switch off its breaker, wait a minute, and restore power.
If No Comm returns, check the wine temperature with a thermometer, since you cannot rely on the display.
Book a visit if the message persists.

What not to do
