⚠️ IMPORTANT — PLEASE READ BEFORE ORDERING
- This item is currently on backorder. Stock is not immediately available. Estimated lead time is 2–10 business days before shipment. Contact Parts4Tubs to confirm current availability before ordering.
- Special-order, non-returnable. Circuit boards cannot be resold as new to another spa owner. Once ordered, this item cannot be returned or cancelled.
- Leisure Bay-specific design — single pump system. This board supports one pump (Pump 1), a 12V spa light, ozone, and a circulation pump. It does not have a Pump 2 relay output.
- Topside connector is an 8-pin (RJ-45) phone-style plug. This is a Leisure Bay-format connector, not the Balboa Molex connector used on VS, EL, or BP series boards.
- ⚠️ Non-Leisure Bay topsides require a custom adapter plate AND DIP switch 2 set to OFF. If you are replacing your topside with a standard Balboa VL-series panel, you must use a custom adapter plate AND turn DIP switch 2 off. Without both, the panel will not function correctly.
- Identify by board part number and chip number. Look for chip LB500SR1(x) on the white label on the board. The board part number 53409 should also appear on the board label.
- Contact Parts4Tubs before ordering to verify compatibility with your specific Leisure Bay spa model.
