The Village Marine Tech MST‑08139 (20‑0386) is the main control board for a marine RO watermaker master controller. Common failure modes include damaged power‑input fuses or capacitors, burnt relays on the pump/valve drive circuits, and firmware corruption that triggers “master fault” codes. First‑check steps are to verify the 12 V DC supply and ensure proper voltage at the board’s input terminals, inspect all solder joints and relay contacts for burn marks, and review any stored error logs or diagnostic LEDs on the panel.[oss-gpt-20b] |
