Larko 01008 Gate Controller

Larko 01008 is the main motherboard assembly for the Larko Mark 1 gate operator; it hosts the LEDs, transformer and fuse block that distribute power to the logic and power boards. Common failure modes include blown or corroded fuses, a failed transformer winding, or shorted LED drivers, often caused by over‑voltage spikes from the gate drive circuitry. First‑check steps: verify input voltage and polarity at the board’s supply terminals, inspect each fuse for continuity and look for burn marks on the transformer windings; then test the transformer output with a multimeter to confirm proper secondary voltages before proceeding to component‑level diagnostics.[oss-gpt-20b]
