Quick answer
Lo on a DCS outdoor refrigerator is a low temperature alarm: 10 degrees or more below the set point for over 1 hour.
Model compatibility: DCS reuses codes across series and model years, so Lo 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
Low temperature alarm: compartment 10 degrees or more below set point for over 1 hour.
Seeing Lo on a DCS RF24RE3 or RF24LE3 outdoor refrigerator? It is a low temperature alarm. The compartment has gone colder than your set point by 10 degrees or more and has stayed that way for over an hour.
Silencing it
A press of any key mutes the audible part. Muting does not clear the condition, so the code keeps flashing until the temperature is corrected.
A DCS outdoor refrigerator in Los Angeles that stays on Lo can be reported at (310) 616-5236. The refrigerator repair page gives more. Tell us the model number and the set point you use.
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.
