Description
Coast Spas BP501 main board replacement for restoring a spa pack whose control electronics have failed. The main board reads the topside panel and sensors, then switches power to pumps, heater and accessories. Swapping the board is often quicker and less costly than replacing the entire pack when the enclosure and heater are still sound. Check that your pack is a BP501 and note how every plug is connected before you remove the old board.
