Quick answer
3CA on a Samsung heat-pump dryer is an inverter compressor error that calls for service.
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
3CA is an inverter compressor error on Samsung heat-pump dryers.
A 3CA message on a Samsung dryer means an inverter compressor error, described by Samsung as the inverter compressor not working correctly. It is listed for heat-pump dryers, so a dryer without a heat pump will not show it.
Samsung gives no owner steps for this code. Unplug the dryer if you need to leave it alone, and note the code before you call.

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.
