Jandy 6473-E Circuit Board

The Jandy 6473‑E is a control‑panel PCB used in AquaLink pool and spa power centers, housing the main microcontroller, I/O interfaces, and button circuitry. Common failures on this board include burned or tripped fuses, damaged surface‑mount components (especially under the reset button), and shorted power traces from water ingress; these often manifest as a blank display or intermittent reset behavior. First‑check steps: verify 12 V/24 V supply to the board, inspect for visible corrosion or burnt spots on the PCB, and test I/O pins with an oscilloscope or multimeter for continuity and proper voltage levels.[oss-gpt-20b]
