Sunlight Saunas 547-1B-CM Control Panel Repair Service

Professional diagnostic and board-level repair service for this Sunlight Saunas 547-1B-CM Control Panel.

The Sunlight Saunas 547‑1B‑CM is an infrared sauna control panel that integrates a touch‑pad interface, temperature and time settings, and audio/chromotherapy controls onto a single PCB. Common failure modes for this unit include burnt or tripped power supply components (often due to low‑quality commercial grade supplies), dead or miswired touch‑pad LEDs, and intermittent relay contacts in the heating element driver circuit. First‑check diagnostics: verify 120 VAC input and correct DC output rails on the board; inspect the power supply for overheating, blown fuses, or damaged capacitors; test all I/O pins to the touch pad and relays with a multimeter and confirm no open circuits or shorted lines.
