Jandy Industries 8124A Circuit Board

The Jandy Industries 8124A is the primary control PCB for the AquaLink Power Center, handling power distribution, relay sequencing and interface to the pool’s automation system. Common failure modes include blown 3 A fuse or downstream fuses, damaged capacitors on the 25 VAC input line, faulty relays that lock in a closed state, and shorted trace paths caused by moisture ingress or thermal stress. Begin diagnostics by verifying the 25 VAC supply to the board, inspecting the 3 A fuse and any connected fuses for continuity, then visually inspect the PCB for cracked solder joints, bulging capacitors, or burn marks; if all pass, test relay contacts with a multimeter and check for proper voltage levels at the relay coil terminals.[oss-gpt-20b]
