Jandy Industries 6473-E Circuit Board

The Jandy Industries 6473‑E is an Aqualink RS8 pool/spa control panel that integrates a full‑color LCD, button interface, and wired I/O for heater, filter, and pump modules. Common failure points include the power supply board (often a failed regulator or blown capacitor), the main controller PCB (burnt traces or damaged ICs), and the user‑interface buttons (shorted contacts). For troubleshooting begin by verifying 24 V DC input to the panel, inspecting the power supply for proper output voltage and ripple; next check all I/O connections for continuity and correct wiring; finally review any error codes displayed on the LCD and visually inspect the PCB for burn marks or loose solder joints.[oss-gpt-20b]
