The Jacuzzi® 51424 / Balboa BH136 circuit board is a factory-style replacement PCB for select legacy Jacuzzi spa control systems using the analog H136 platform. This board is used with one-pump Jacuzzi systems and connects to the topside control using the phone-style RJ plug.
This is the correct replacement board when your existing board, chip sticker, and cabinet wiring diagram match the BH136 / 51424 configuration. Because these older Jacuzzi boards are increasingly limited in supply, verifying the existing board before ordering is strongly recommended.
