What is the condition of this circuit board?
This is a new circuit board sold by Western Tub and Pool. If you have questions about the condition of a specific board in our inventory, please contact us before ordering.
Does this board come pre-configured?

Important Installation Notes
Circuit boards are not plug-and-play. Before installing, please note the following:
Correct component voltage setup is required — component wires on the board may need to be moved
DIP switches must be configured correctly for your system
Some configuration on the topside panel may also be required
Always reference the wiring schematics on the back of the spa pack cover
Do not select a board based on appearance — many boards look nearly identical but contain different software or chips
Electrical or physical damage resulting from improper installation voids the manufacturer's warranty
If you are unsure about any step of the installation process, we strongly recommend engaging a qualified spa technician.
Frequently Asked Questions
How do I know if this is the right circuit board for my hot tub?
The most reliable way to confirm compatibility is to match the Model Number from your spa control system's ID label — typically found on the top of the control box. You can also check the part numbers listed above or contact our team directly.
Can I send in photos to confirm the right part?
Absolutely. Email us at fixmytub@gmail.com with photos of your existing board, your hot tub's make and model, and the serial number. Our team will confirm whether this is the right replacement before you order.
Does this board come pre-configured?
Configuration options may be available depending on where you order. Contact us at 1-855-248-0777 to discuss your specific electrical setup, including your service voltage, pump configurations, and ozonator circuit requirements.
Can I return a circuit board if I order the wrong one?
Circuit boards are non-returnable electrical items, as they cannot be resold once handled. That's why we strongly encourage you to verify your part number or contact us before placing your order.
What warranty does this circuit board come with?
This board is backed by a 1-year limited warranty from Balboa Water Group, covering manufacturer defects. Damage from improper installation or incorrect PCB selection is not covered under warranty.
Does my hot tub need to be serviced by a professional?
If you're comfortable with basic electrical work and spa systems, many owners complete this replacement themselves. However, if you're unsure about voltage configurations or wiring, professional installation is always recommended.

Important Installation Notes
Circuit boards are not plug-and-play. Before installing, please note the following:
Correct component voltage setup is required — component wires on the board may need to be moved
DIP switches must be configured correctly for your system
Some configuration on the topside panel may also be required
Always reference the wiring schematics on the back of the spa pack cover
Do not select a board based on appearance — many boards look nearly identical but contain different software or chips
Electrical or physical damage resulting from improper installation voids the manufacturer's warranty
If you are unsure about any step of the installation process, we strongly recommend engaging a qualified spa technician.
Frequently Asked Questions
How do I know if this is the right circuit board for my hot tub?
The most reliable way to confirm compatibility is to match the Model Number from your spa control system's ID label — typically found on the top of the control box. You can also check the part numbers listed above or contact our team directly.
Can I send in photos to confirm the right part?
Absolutely. Email us at fixmytub@gmail.com with photos of your existing board, your hot tub's make and model, and the serial number. Our team will confirm whether this is the right replacement before you order.
Does this board come pre-configured?
Configuration options may be available depending on where you order. Contact us at 1-855-248-0777 to discuss your specific electrical setup, including your service voltage, pump configurations, and ozonator circuit requirements.
Can I return a circuit board if I order the wrong one?
Circuit boards are non-returnable electrical items, as they cannot be resold once handled. That's why we strongly encourage you to verify your part number or contact us before placing your order.
What warranty does this circuit board come with?
This board is backed by a 1-year limited warranty from Balboa Water Group, covering manufacturer defects. Damage from improper installation or incorrect PCB selection is not covered under warranty.
Does my hot tub need to be serviced by a professional?
If you're comfortable with basic electrical work and spa systems, many owners complete this replacement themselves. However, if you're unsure about voltage configurations or wiring, professional installation is always recommended.

How to Identify Your Circuit Board
Ordering the wrong circuit board is a costly mistake — and an easy one to make, because many Balboa boards look nearly identical. Here's how to make sure you're ordering the right one:
Locate the chip number: Find the small white sticker near the center of your existing circuit board. The chip number — not the board's appearance — is what identifies it.
Note your five-digit board number: Most Balboa boards have a five-digit number (e.g., 54383) printed or labeled on the board.
Gather your spa details: Your spa's make, model, and serial number will help us cross-reference your part quickly.
Send us a photo: If you're unsure, email a clear photo of your existing board to fixmytub@gmail.com and our team will confirm the match.
Important: Do not order a circuit board based on looks alone. Multiple boards share the same appearance but contain different chips and software. Always verify using the chip number or contact us first.
