Cedrus 547-1A-PS Power Supply Repair Service

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

The Cedrus 547‑1A‑PS is a power supply unit used in infrared sauna systems, providing regulated DC output to the heating elements and control board. Common failure modes include tripped or blown internal fuses, degraded capacitors on the rectifier/filter stage, and faulty MOSFETs that cause overheating or shutdown; error code R05 often points to sensor or controller board issues. Initial diagnostics should verify mains input voltage and polarity, check output voltages against spec, inspect for visual signs of component damage (burn marks, bulging caps), and review the sauna’s error log for recent fault codes.
