Raypak 601588 601587 Circuit Board

The Raypak RP‑2100 Control Board (part numbers 601588/601587) is the main processor for industrial pool and spa heating units, providing digital display, temperature regulation, and safety interlocks. Common failure points in this class of boards include burned or cracked power traces, failed MOSFETs or op‑amps, and degraded capacitors that can cause erratic temperature readings or loss of communication with the heater module. First‑check diagnostics: verify 24 V DC input to the board, inspect for visible burn marks or loose solder joints, and confirm that the digital display and status LEDs are functioning; then review any error codes logged by the unit’s diagnostic port.[oss-gpt-20b]
