Why Lo appears
On DCS RF24RE3 and RF24LE3 outdoor refrigerators, Lo means the compartment has sunk at least 10 degrees under the set point, and has done so for over 1 hour.
Signs on the panel
The word Lo blinks.
A sound repeats once per second.
The Alarm LED in the top left corner, beneath the label Alarm, is lit.
Silencing
Press any key to stop the noise. The condition itself is untouched, so the display keeps flashing until the temperature is put right.
Ring (415) 969-2271 if your outdoor unit in San Francisco or the Bay Area will not leave Lo, or browse DCS refrigerator repair first. Quote the model number and your set point.
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
Lo is a low temperature alarm: the compartment is 10 degrees or more below set point for over 1 hour.
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.
