Gecko Spa Pak INYE-3 4kw Heater North America

The Gecko Spa Pak INYE-3 with 4kW Heater (PAK-202000) is the complete Gecko-based control pack for Arctic Spas equipped with the standard (non-Onzen) Gecko INYE-3 system. Includes the Gecko motherboard and integrated 4kW heater in one sealed equipment-bay housing. The non-Onzen sibling of the INYE-5.

When you'll need a full Spa Pak: Replace the entire INYE-3 Pak when the motherboard or integrated heater has failed catastrophically and component-level repair isn't viable — typically lightning damage, severe water intrusion into the equipment bay, or end-of-life on a 12+ year old spa. For isolated failures (single fuse, dead pump, bad pressure switch), replace just that component first.

Will this fit my spa? Yes, on Arctic Spas originally configured with the Gecko INYE-3 + 4kW heater system without Onzen. If your spa has the Onzen salt water system, you need the Gecko Spa Pak INYE-5 instead (Onzen-compatible variant). Bring the part-number sticker from your current pack to one of our three Ontario showrooms for matching before ordering.

Important: Pack replacement is a service-tech job. 240V electrical work, GFCI integration, and full system commissioning are involved. Don't attempt as a DIY project.
