Cedrus 547‑1B‑PS is a power supply module used in Cedrus sauna units to regulate the heating element and control circuitry. Common failures include degraded electrolytic capacitors on the input side, burnt-out voltage regulators or MOSFETs due to overheating, and shorted output traces from moisture ingress. First‑check steps: verify incoming mains voltage and measure output rails with a multimeter; inspect for bulging or leaking capacitors and check for any burn marks on IC packages; review any error codes displayed on the sauna controller panel for indications of power supply faults.
