Display harness issue
Code 30 refers to the display harness of an ActiveSmart indoor integrated DCS refrigerator, RS/RF series. Even though the fault concerns the display, the message does not appear as words: it comes as alarm beeps in a count or as LEDs flashing in binary.
Response
The alarm mute button silences it on ActiveSmart.
The repair itself belongs to a service technician.
The refrigerator gives no sentence to read. Count the beeps or note the binary LED sequence if you want to confirm it is 30 before calling, and keep in mind that muting the alarm silences it without repairing the harness.

Model compatibility: DCS reuses codes across series and model years, so 30 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
