Error codeNo Comm
ApplianceIce Maker
Quick answer
No Comm means the clear ice machine lost communication to its display. The manual says to cycle power and then call Customer Care.
Model compatibility: U-Line reuses codes across series and model years, so No Comm may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Unit lost communication to the display.
No Comm means the unit lost communication to the display. It is listed for the U-3018CLRS-40B, a 3000-series clear ice machine, and it is a current-generation code.
What to try first
Disconnect power to the unit, then reconnect it. If the message keeps coming back, the manual says to contact Customer Care.
What a technician checks
For a persistent No Comm the manual’s service procedure covers the communication cable between the user interface and the main control board, with voltage checks at both ends. Replacing the interface, the board or the cable follows from those results, so it is technician work and not an owner task.
