(DISCONTINUED BY MANUFACTURER)

SEE REPLACEMENT PART: OBSOLETE

When a Leisure Bay system using a Heat Jacket setup begins acting inconsistently, the board is often the deeper cause. This replacement board is designed for compatible Heat Jacket Leisure Bay applications where the original board no longer coordinates the heater and the rest of the pack with the steadiness the spa needs.

That kind of failure tends to affect the entire feel of the spa. Temperature regulation may drift, controls may stop feeling dependable, and the pack can gradually lose the sense of order that makes a spa easy to trust. Replacing the correct board addresses the system at its control center instead of reacting to surface-level symptoms.

The Heat Jacket and Leisure Bay pairing matters because this is not just a generic board. It is meant to preserve a specific equipment relationship and operating style. That is what makes proper application such an important part of the repair.

Once installed in the right Leisure Bay setup, this board helps the spa regain smoother coordination and a more reliable day-to-day operating pattern.
