Product Overview
The Jandy R0456500 Temperature Sensor Kit plays a vital role in your heater’s control system by monitoring the water temperature and supplying accurate data to the onboard logic. In the heater’s thermal control loop, if the sensor fails or degrades, it can cause errant readings such as “shorted H₂O sensor” errors or the heater refusing to fire. 

This OEM kit ensures an exact fit with LXi, JXi and Legacy series heaters and restores the original sealing arrangement with the included sleeve and gasket. For installers and pool service professionals, replacement of the R0456500 is a recommended maintenance step when seeing temperature-sensor faults or during full controller or manifold rebuilds. It delivers reliable performance and supports the heater’s safe and efficient operation over time.
