RELAY 7 BROKEN, explained
This text is how a U-Line blast chiller reports that its electronic board found a failure on relay 7. The manual’s answer is to call service.
What you can do
Because the board itself holds the fault, there is no step for the owner to carry out. At most, open the ALARM tab, confirm what was recorded and note the relay number before calling.
Which chillers use it
The touch screen controller on the UCBF659, UCBF559, UCBF632, UCBF532 and UCBF432.
Easily confused alarms
RELAY 1 BROKEN: a separate relay failure reported by the same board
RELAY 3 BROKEN: another numbered relay alarm, easy to read as this one
San Francisco blast chiller service
If your chiller is in San Francisco or the surrounding Bay Area, call (415) 329-7078. It speeds things up to quote the relay number on screen, the model number and any earlier attempts. See also U-Line freezer repair.
Model compatibility: U-Line reuses codes across series and model years, so RELAY 7 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.
