Cedrus Sauna 547-1B-PS Controller
 |
Cedrus Sauna 547‑1B‑PS is a control board that manages infrared heater operation, temperature regulation, and safety interlocks in residential/commercial saunas. Common failure modes for this class of units include burned or tripped power supply components, degraded MOSFETs or driver ICs, and corrupted firmware or lost calibration data; these often present as no heating, intermittent operation, or error codes related to over‑temperature or power faults. First‑check diagnostics: verify the 120 V/240 V input voltage and ensure the main PSU is delivering correct output rails (12 V, 24 V, 48 V as specified); inspect for visible burn marks, swollen electrolytic capacitors, or loose connections on the board; and review any displayed error codes or LED status indicators to pinpoint a specific subsystem fault.[oss-gpt-20b] |
