Quick answer
The 3CA family of codes on a Samsung AirDresser involves the compressor motor and main PBA.
Model compatibility: Samsung reuses codes across series and model years, so 3CA, 3CA1, 3CA2, 3CA3, 3CA4 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
Compressor motor defective or not connected properly, or defective main PBA.
The codes 3CA, 3CA1, 3CA2, 3CA3 and 3CA4 all belong to one entry for the Samsung AirDresser.
Possible causes named by Samsung
The compressor motor is defective.
The compressor motor is not properly connected.
The main PBA (control board) is defective.
Checking a motor connection or a board is technician work. Nothing in Samsung’s list asks the owner to open the cabinet.

3CF also lists the main PBA among its causes, but for the upper fan motor.
1C1 is a steam chamber sensor code, easy to mix up with motor faults.
