Understanding Your Spa Circuit Board

How to Identify Your Spa Control System Circuit Board

This guide explains how to identify your spa control system circuit board by using either the Balboa circuit board part number or, if the original sticker is missing, the primary chipset number on the board.

Over time, the white sticker on a circuit board can crack, loosen, or fall off completely. When that happens, the chipset number can often be used to cross-reference the correct board.

If you are not comfortable identifying, removing, or replacing circuit boards, contact a qualified spa technician before attempting any repair.

Where to Look on the Circuit Board

Locating your spa circuit board part number and chipset number

Two Ways to Identify the Board

Use the Circuit Board Part Number

If the original sticker is still attached, look for the Balboa part number. It is usually the first set of numbers and often starts with “5.” The number may be five digits long, such as 54115, or five digits followed by a dash and two additional digits, such as 54115-02.

Use the Primary Chipset Number

If the sticker is missing, look at the largest chip on the board. The top set of numbers is usually the primary chipset number. In the example image, the chipset number is LITELDR1A.

What to Do After You Find the Number

Search by Part Number

Use the circuit board part number to search our website. If the part is available, the exact board or related replacement information should appear in the search results.

Search by Chipset Number

If the board sticker is gone, use our Circuit Board Finder and choose the option to locate the circuit board by chipset number.

Consider a Retrofit Kit

If the circuit board is no longer made by Balboa, you may need to replace the entire spa control system. Balboa Value Pack Retrofit Kits are complete replacement solutions for many hot tubs. In some cases, replacing the full control system can be close to the cost of the replacement circuit board and may give the spa a more reliable long-term repair.
