FIND YOUR CIRCUIT BOARD FAST AND EASY USING OUR CIRCUIT BOARD FINDER

Feature-defined systems need a board that matches the specific mix of functions the spa was built to support. This Leisure Bay LB501SZR1 Serial Standard board is designed for compatible applications controlling Pump 1, Pump 2, Light, Ozone, and Circulation, making it the right choice when the original board has started to lose that coordinated behavior.

When the board in a system like this begins to fail, the symptoms can seem scattered because several functions are affected by the same central logic. The spa may stop feeling smooth and dependable, not because every accessory is failing, but because the board is no longer keeping them organized correctly.

The P1-P2-LT-OZ-CIRC configuration is a big part of what defines this board. Matching that exact environment helps preserve the original design of the pack and keeps the repair from becoming a compromise that only partly fits the spa’s needs.

Installed in the correct Leisure Bay system, this board helps restore steadier control across all of those functions and gives the spa a more reliable, more confidence-inspiring feel overall.

Replacement board for compatible Leisure Bay LB501SZR1 systems
Supports Pump 1, Pump 2, Light, Ozone, and Circulation functions
Helps restore coordinated control across multiple pack features
Useful when broad system behavior becomes inconsistent
Improves overall reliability and daily usability
