nC2 in plain words
Samsung heat-pump (condenser) dryers show nC2 along with the text Check inner cover of heat exchanger. The fault concerns the internal cover of the heat exchanger.
Owner check
Look over the cover assembly.
Confirm the inner cover of the heat exchanger is seated correctly. The Russian list blames an improperly installed inner cover.
If nC2 is still shown, Samsung UK says to contact support for service.
Dryer service for San Francisco and Bay Area owners
With the cover correctly placed and nC2 still on screen, call (415) 969-6153 about Samsung dryer repair. Tell us the code and the model number.
Model compatibility: Samsung reuses codes across series and model years, so nC2 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
nC2 reports a problem with the internal cover of the heat exchanger on a heat-pump dryer.
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.
