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.

  • Essential Power Management – Controls the distribution of electricity within Finlandia and Harvia sauna systems, ensuring reliable operation of heaters, timers, and thermostats for safe and efficient sauna performance.
  • High Performance – Manages incoming power and internal relays to maintain predictable, stable heater responses, contributing to consistent temperature control and overall system efficiency.
  • Durable Construction – Built with robust, heat-resistant components to withstand elevated temperatures and humid conditions, minimizing premature failures and extending the lifespan of your sauna’s electronics.
  • Seamless Integration – Designed as a direct-fit replacement for Finlandia and Harvia power supply units, enabling straightforward installation with minimal wiring adjustments.
  • Reliable System Protection – Helps safeguard downstream components by maintaining proper electrical control, preserving the safety and integrity of your sauna system.
