Error code3CA
ApplianceDryer
Only heat-pump dryers from Samsung use 3CA, and it points to one thing: the inverter compressor is not working correctly. A dryer of another type does not carry this entry.
What Samsung provides
No steps for the owner appear in the Samsung listing.
Leave the dryer switched off until it has been looked at.
5C, 5E: a drainage malfunction on heat-pump dryers.
AC6, AE6: trouble between the main and inverter boards.
Samsung dryer service in the Bay Area
A heat-pump dryer showing 3CA needs more than an owner can do, so contact Samsung dryer repair in San Francisco or the Bay Area at (415) 969-6153. Say that the display reads 3CA and give the model number.
Model compatibility: Samsung reuses codes across series and model years, so 3CA 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
Inverter compressor error.
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.
