The alarm in one line
The controller of your U-Line blast chiller has flagged relay 5 as faulty. The manual words it as a failure detected on relay 5 by the electronic board, and the response it gives is to call service.

Reading the ALARM tab
Alarms recorded during a cycle can be viewed in the ALARM tab. If a relay alarm other than this one is listed too, such as RELAY 7 BROKEN, tell the technician. Relay faults sit on the board, so they are not an owner repair.
Repair help for a blast chiller in San Francisco
San Francisco and Bay Area owners can reach us at (415) 329-7078. Say that relay 5 is named on the display and give the model number, plus whatever you have done so far. Our U-Line freezer repair page covers the service itself.
Model compatibility: U-Line reuses codes across series and model years, so RELAY 5 BROKEN may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
The control board found relay 5 faulty; the manual says to call service.
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.
