Circuit Board Finder
Search any circuit-board number, Balboa system number, model, model number, spa brand, or cross-reference. The Finder identifies what you have and, where possible, points you directly to the circuit board or current replacement you can buy.
Important: Many older Balboa circuit boards and spa control systems are no longer supported. When no direct circuit-board replacement remains, the practical replacement path is often a complete modern spa control system matched to the spa's heater, pumps, blower, circulation pump, topside panel, voltage, and accessories.
Find Your Circuit Board
The strongest match appears first. Partial searches also show exactly which field or cross-reference matched.
Search Results
How results are handled: available boards link directly to the product. Discontinued boards with a verified replacement link to that replacement. Historical systems with no direct board replacement point to the replacement-control-system section instead of sending you through a chain of obsolete parts.
