When selecting your spa circuit board, it’s critical that you go by part numbers and not appearances or the model number. The part number on a spa circuit board can be found on a white sticker located directly on the circuit board (The ID label may be located on the board relays or on the transformer). Buy based on this part number. Model numbers of a circuit board may provide many different options and/or lead to ordering the wrong part. Do NOT purchase a hot tub circuit board just because it looks the same as the one you’re replacing and have a similar model number. Spa circuit boards can look identical, but be programmed differently to work with different spa controllers and topside panels. NOTE that most circuit boards need to be configured in the field to work with the existing spa components and power ratings, and a licensed professional is recommended for installation and configurations. If this circuit board is being used as an optional replacement for the original circuit board, please follow the new circuit board wiring diagram for proper installation and configuration setup.

CIRCUIT BOARD PURCHASE AGREEMENT: Manufacturer's Warranty DOES NOT cover burnt terminal blocks or connections, burnt or blown fuses, burnt traces or terminals for circuit board purchases. These are normally caused by field installation errors, loose connections and/or over current draw from external electrical wiring and/or components. This warranty agreement applies to ALL orders made over the phone, online orders, and through purchase orders
