Professional diagnostic and board-level repair service for this 030920120036 547-1-PS Power Supply.

The 030920120036 547‑1‑PS is a commercial‑grade sauna power supply used in Sunlight/Cedrus style infrared units. Common failure modes for this class include failed electrolytic capacitors on the input/output stages, overheating of the internal transformer or rectifier bridge, and degradation of the output voltage regulator due to thermal cycling. First‑check diagnostics: verify that the unit receives proper mains voltage and that all input fuses are intact; inspect the board for bulging or leaking capacitors and any scorch marks around the transformer windings; then measure the regulated 25 VDC output with a multimeter while the supply is powered on to confirm correct voltage levels.
