Tip: The serial number is shown on the sticker preceded by S/N or P/N (part number).
Tip: The image above shows an example of a serial number sticker (click image to enlarge it).

Verify the serial number on the old circuit board being replaced is in this list.

Serial Numbers:

• 54640
• BAL54640

Step 2 of 2:
Tip: Locate the chip number on the circuit board you are replacing.
Tip: The whole chip number is on a sticker located on the circuit board (not the box).
Tip: This is a different sticker than the serial number sticker.
Tip: The chip number sticker usually has two lines of text and the top line is the whole chip number (the bottom line is not needed).
Tip: See image above for an example of a chip number sticker and where they're typically found on the circuit board (click the image to enlarge it).

Verify the chip number on the circuit board being replaced placed is in this list.

Chip Numbers:

• VS514SZR1A
• VS514SZR1B

Additional Cross Ref., Compatibility & Installation

This is a fully compatible alternate replacement.

ATTENTION: Set all wires the same as how they are on the old circuit board.

For systems with an expander circuit board, set dip switch A7 to the ON position.
Tip: An expander circuit board is about 2" wide by 3-1/2" long and is usually mounted on top of the heater.
Note: Expander circuit board is not included.

For systems with a circulation pump, set dip switch A9 to the ON position.
Tip: A circulation pump is not a jet pump.

Set all other dip switches the same as how they are on the old circuit board.

System Control Box Serial Numbers

Tip: The system control box is usually located below the hot tub and the circuit board mounts inside of it.

Please note: System control box serial numbers cannot identify a circuit board.
Please note: Do not use this section for confirmation of making the correct purchase.

The Balboa 54640 VS514SZR1(x) circuit board can be found in the following hot tub system control boxes (but not limited to).

System Control Box Serial Numbers:

• 54639
• Model Number: VSP-VS514SZ-YCAH

Tip: When replacing a hot tub circuit board, testing the heater and replacing it (if bad), is recommended before installing or applying voltage on a new circuit board.
Note: A continuity test is not a sufficient heater test. Contact us by phone for more details on testing a heater.
See RELATED PRODUCTS below for heater replacements.

Tip: Burned circuit boards or burned heater relays are often due to a loose electrical connection or a bad heater or both.
If all connections are tight and if the heater is good then the heater relays are probably old and worn out.
If a burned relay was powering a pump and all electrical connections are tight then the relay is probably old and worn out or the pump might be bad or going bad or all three.
Replacing the heater and/or pump with a new one is recommended if any of those scenarios apply.
