Ambient heater fault
Printed words never appear for this fault, so pay attention to the sound and the lights. Binary LED flashing or a run of alarm beeps stands for code 13 on an ActiveSmart indoor integrated DCS refrigerator (RS/RF series). The fault named is the ambient heater, and nothing is written on screen.
The refrigerator, then, communicates through the number of beeps or the arrangement of its flashing LEDs; matching that to code 13 is how you know the heater is the subject.
Do and do not
Do press the alarm mute button to stop the beeping.
Do not expect to fix the heater yourself; a service technician is needed.
Dial (415) 969-2271 from San Francisco or anywhere in the Bay Area, or read DCS refrigerator repair beforehand. Say that code 13 is showing, give the model number and add what you tried, such as muting the alarm.
Model compatibility: DCS reuses codes across series and model years, so 13 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
