No screen, so listen and look
ActiveSmart indoor integrated refrigerators in the DCS RS/RF series never print a fault on a display. Code 1 is a module failure, and the refrigerator communicates it by sounding a number of alarm beeps or by lighting its LEDs in a binary pattern.
Steps to take
Press the alarm mute button to silence the unit.
Arrange for a service technician, since the module needs one.
Calls from San Francisco and the surrounding Bay Area can go to (415) 969-2271, and the DCS refrigerator repair page explains the work. Count the beeps or note the LED pattern first, and keep the model number on hand.
Model compatibility: DCS reuses codes across series and model years, so 1 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
Module failure, reported through alarm beeps or a binary LED flash pattern rather than text.
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.
