Professional diagnostic and board-level repair service for this Larko Electronic 24-02 Circuit Board.
Larko Electronic 24‑02 is the logic board that drives the ERD (electronic remote door) and timer circuitry on a Larko Mark 1 gate operator. Common failures on this board are voltage regulator dropout or capacitor leakage, which manifest as intermittent loss of control signals or erratic timer behavior. First‑check steps: verify 24‑V input to the board, inspect for burnt components or bulging electrolytics; test dip‑switch settings against the service manual (ERD and timer modes); and review any error codes on the operator’s display for clues to a logic fault. |
