Larko 24-02 Circuit Board
 |
The Larko 24‑02 is the main logic/control board used in Larko Mark 1 gate operators, housing DIP switches that set ERD and timer functions along with a timer potentiometer. Common faults on this board include shorted or open traces around the switch matrix, burnt-out MOSFETs or ICs due to over‑voltage spikes from the power board, and degraded capacitor electrolytes causing intermittent logic resets. First‑check steps: verify 24 V DC supply continuity to the board, inspect for visible burn marks or loose solder joints on the DIP switch area, and read any diagnostic codes displayed by the gate operator’s indicator LEDs before proceeding with component replacement.[oss-gpt-20b] |
