DOORKING 1871-010 CIRCUIT BOARD
 |
The DOORKING 1871‑010 is the main control board for the DoorKing 1812 “Classic” residential intercom system; it houses the central processing unit and associated I/O circuitry. Common failure points include a burned or failed CPU, damaged power‑rail traces, or defective relay drivers that can cause loss of audio/telephony function or intermittent lockout. Because the board is not programmable via telco line—only Ethernet—firmware corruption will prevent remote configuration, so check the firmware checksum and reset to factory defaults if necessary. First‑check diagnostics: verify 12 V DC supply stability at the board’s input; inspect for visible burn marks or loose solder joints on the CPU and relay driver ICs; and review any error logs or LED status codes displayed by the intercom unit.[oss-gpt-20b] |
