Balboa Circuit Board and Chip Cross Reference Guide
It’s pretty easy to identify your Balboa circuit board using its unique serial number. Most hot tubs and spas have a sticker on the circuit board indicating the model number. But if for some reason you’re unable to find the serial number, don't worry, there’s still a way to track your replacement down. Just use this helpful cross reference guide! All you need is your balboa circuit board chip number and you’ll be ready to go.
Balboa Circuit Board & Chip Serial Number Reference Chart
Not sure where to find the circuit board chip number? Look for a small white sticker on either the front or back of the board. If you don't see a white sticker, it might be branded, engraved, or written on the back of the board. Once you've located the chip number, use the following reference chart to find your circuit board number.
