FAQ

This sensor is compatible with Zodiac and Jandy Legacy LRZE, LRZM, JXI, and LXI series pool and spa heaters, specifically the 125, 175, 200, 250, 260, 300, 325, and 400 models.
This unit serves as a direct replacement for OEM part number R0456500. It also cross-references with R0456600, R0477300, R0523900, and the 6204-209 thermistor.
If your heater is displaying inaccurate water temperature readings, failing to fire when the set temperature is reached, or showing specific sensor-related error codes on the control panel, the thermistor probe may be faulty. It is responsible for detecting the water temperature as it enters the heater, so a failure often prevents the system from cycling correctly.
Replacing the sensor is a straightforward process that typically takes 15 to 30 minutes. You will need basic hand tools to access the heater's electrical compartment and remove the old probe. Ensure the power to the heater is completely disconnected at the breaker before beginning any work.
Before installation, ensure the pool pump is turned off and the system is depressurized to prevent water leakage when removing the old sensor. When installing the new probe, ensure it is seated properly to maintain an accurate seal and connection to the heater’s control board.
