Doorking 1871-010 Board

The Doorking 1871‑010 is the main control board (CPU) used in the DoorKing 1812 “Classic” residential gate and access‑control systems. Common failure points include power‑supply overvoltage or brown‑outs to the board, shorted I/O terminals on the 1812 terminal block, and firmware corruption that prevents the unit from responding to remote or telephone inputs. First‑check diagnostics: verify the 12 V DC supply rail to the board with a multimeter; inspect all solder joints and terminal connections for cracks or burn marks; review any stored error codes via the system’s diagnostic LED pattern or serial console, if available.[oss-gpt-20b]
