DCS Refrigerator 12 Error Code

VERIFIED

Error code 12
Appliance Refrigerator

Your refrigerator is using beeps or binary LED flashes to tell you about code 12: something is wrong with the ambient heater or with the PC, FC fans.

Where it applies

The entry is written for RS/RF series DCS refrigerators, the ActiveSmart indoor integrated range.

Response

  1. Silence the alarm using the mute button on the ActiveSmart unit.
  2. Contact a service technician, because the issue is not something an owner clears.

Where else to look

  • Code 11, which carries the identical meaning
  • Code 14, an ambient heater fault by itself
  • Code 18, a freezer fan issue
