Nasscor WB8.3 Sauna Unit

The Nasscor WB8.3 is a sauna control unit designed to regulate temperature and timing in commercial sauna environments with a high‑temperature operating range. Common failure modes for this model include malfunctioning control boards (often due to component burn‑out or solder joint fatigue), faulty temperature sensors, relay failures, and power supply instability. Initial diagnostics should verify the 24 V/120 V input voltage and inspect the main board for visible damage or burnt components; check sensor wiring continuity and probe the relay contacts for proper operation; finally review any stored error codes on the display to pinpoint the fault source.[oss-gpt-20b]
