Circuit Boards - PCB
Transformers, fuse holders and circuit boards are readily available for all our Electronic Systems and Controls. Electronic control systems consist of a printed circuit board inside the spa control box.
Wires going into the terminals can work loose due to the pump's vibration, damaging the board. To remedy this, try silicoting screws in the terminal block. If the relays are malfunctioning or board is burnt on front or the back, you will need a replacement PCB.
