Samsung Dryer 3C Error Code — How To Fix It

Samsung dryer showing a 3C error code? The machine is detecting a motor problem — but the motor itself isn't always what's actually failing. Here's the full diagnostic process. This Samsung came to me from another tech who couldn't crack it. The 3C code points to the motor or its sensing system, but as this repair shows, the actual fault can sit in the wiring, the control board connections, or a component the code doesn't point to directly. I walk through every step from power-cord hookup to full disassembly, component testing, and root-cause confirmation.
