Another entry with identical meaning is code 30. For a communication fault look up code 49, and for ice tray trouble see code 24.
Why the display gives no words
Even with a fault in the display harness, ActiveSmart refrigerators stay with sound and light. Counting the beeps or noting the LED sequence lets you confirm it is 31 before you call, and muting the alarm does not repair anything.
Harness repair help in the Bay Area
To arrange DCS refrigerator service in San Francisco or the surrounding Bay Area, ring (415) 969-2271; DCS refrigerator repair explains more. Mention code 31, the model number and whether you muted the alarm.
Model compatibility: DCS reuses codes across series and model years, so 31 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
