Raypak 601587 Circuit Board

Raypak RP‑2100 601587 is the digital control board for pool/spa heaters, handling 24 V input and driving the display/ignition circuitry. Common failure mode is a burnt spot on the PCB (often near the power section), which typically results in loss of display or ignition function; this usually correlates with a faulty transformer or over‑voltage event. First‑check diagnostics: verify 24 V at the board’s input, inspect for visible burn marks or cracked components, and confirm all connectors are seated before replacing the PCB assembly if damage is present.[oss-gpt-20b]
