Description
The Jandy Ignition Control Assembly R0317500 is a factory-original electronic ignition module purpose-built for Jandy Lite2 LD pool and spa heaters, supporting units from 125K to 400K BTU. This assembly governs the complete electronic ignition sequence, orchestrating safe combustion startup and protecting the heater from irregular firing events. As a direct OEM replacement from Jandy, it delivers proven reliability and consistent performance under real-world operating conditions. Swapping out a failing ignition control module during scheduled service eliminates startup problems, strengthens overall system dependability, and helps maximize the working life of your heater. The plug-and-play design allows for rapid installation and minimal downtime.
