Description
Coast Spas replacement circuit board for the spa pack, labeled 501Z on the product listing. It processes commands from the topside control and switches the pumps, heater and lighting circuits. Replacing only the board keeps the enclosure, heater and existing wiring in place. Read the model label on your current board and compare connector positions before ordering.
