Error codeNo Comm
ApplianceWine Storage
Quick answer
No Comm means the unit lost communication to the display on U-Line 3036 dual-zone cabinets.
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
No Comm means the unit lost communication to the display; disconnect and reconnect power, and contact Customer Care if persistent.
When the display of a U-Line 3000 series cabinet shows No Comm, the main unit has lost its link to the display.
Applies to
The U-3036BVWCS-00B 3036 dual-zone model and DWR and ZWC units, where L is the top zone or drawer and R the bottom.
What the manual tells the owner
Disconnect power to the unit and reconnect it.
If the message is persistent, contact Customer Care.
Technician side
For service the manual calls for inspecting the customer user interface and data cable. If it is defective, the entire door is replaced.
For a U-Line wine cabinet or dual-zone refrigerator in Los Angeles, call (310) 879-5776 or see beverage center repair. Say whether power cycling cleared it, and give the model number.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
