OEM Jandy Power Control Board R0366800 is a vital electrical component for Jandy Lite2 LJ pool and spa heaters, managing all operational control functions for models LJ125, LJ175, LJ250, LJ325, and LJ400. This board ensures consistent, safe operation by regulating power to key components, supporting stable heater performance. Engineered to meet exact OEM specifications, it is built to endure harsh poolside environments. The included power conversion plug features color-coded terminals for both 115V and 230V supplies, ensuring correct installation and voltage matching. Routine replacement helps maintain the longevity and reliability of your heating system.

Note: The power conversion plug for the LJ heater is designed with two sidesÑone for a 115V supply and the other for a 230V supply. Each side is clearly marked and color-coded: blue for 230V and white for 115V. Make sure to connect your heater to the correct side based on your supply voltage. The power conversion plug for the HJ model heater, however, is configured to only allow connection to a 115V supply.
