***Circuit boards cannot be returned after they have been installed. Please reach out to us for assistance if you are unsure as to which circuit board you require. Please reach out to us with your hot tubs make, model, and serial number, as well as any photos of the stickers on your existing control box and board. A photo of your existing topside panel would also be helpful.***

Incoming power and heater connection screws/nuts need to be tight and secure. (Heater Connection Screws/Nuts Torque Specs = 30-35 inch lbs.)   

• Failure to properly connect incoming power or tighten heater connections properly can cause heat/resistance/arching and fry the board at these points.
• Damage at these points is caused by a loose connection. This is not a manufacturing defect, and is not covered by the manufacturer’s warranty.
• We also recommend replacing both copper straps on heaters with the new style jump straps, part number 48-0023A.
