Raypak RP 2100 601587 control panel

The Raypak RP 2100 601587 is the control board for a digital pool heater, typically powered by a 24‑V AC supply and driving gas valves, pressure switches, and temperature sensors. Known failures include PCB burnout or ignition of components due to electrical surges; a common symptom is a visibly burnt spot on the board (P/N 601587/601588). First‑check diagnostics: verify 24‑V input at the transformer terminals, inspect the PCB for burn marks or cracked traces, and review any error codes displayed on the heater’s panel. If power is present but the board shows damage, replace the control board; otherwise, troubleshoot upstream voltage regulators or surge protection devices.[oss-gpt-20b]
