Finlandia / Harvia Part # WX361 Circuit Board for power supply is the factory-engineered electronics package that keeps your sauna’s power unit distributing electricity safely and efficiently. Designed specifically for Finlandia and Harvia systems, this board manages incoming power, internal relays, and control signals so heaters respond predictably to timers and thermostats. Robust components and heat-resistant construction help it withstand the elevated temperatures and humidity found in sauna equipment spaces, reducing nuisance faults and premature failure. As a direct-fit replacement, it drops into compatible power supply housings with minimal wiring changes, making service straightforward for qualified technicians. Replacing a failed or unstable board with this genuine Finlandia / Harvia circuit board restores stable operation, protects downstream components, and maintains the performance and safety margins your sauna was originally designed to deliver.
