Balboa Circuit Board - INF107 VS501Z (54357-03) alliedinnovation using a properly matched assemblyA circuit board like this INF107 VS501Z replacement matters because it restores the control behavior the spa was originally built around. When that central board begins to weaken, the system often starts acting in ways that seem random at first. Heat may drift, pumps may not respond consistently, and the overall pack can feel like it is slowly losing its stability.
