For another temperature-related Hayward replacement part, compare this item with the Hayward GLX-FLO-RP-25 bridge temperature sensor before choosing the correct sensor for your system.
Compatibility Notes
This replacement kit is intended for select Hayward salt chlorine generator, Aqua Rite, Aqua Logic, Pro Logic, and related compatible systems. It should not be treated as a universal temperature sensor for every pool controller or salt system.
If you are checking compatibility with an in-ground Hayward salt system, the Hayward W3AQR15 AquaRite salt chlorination system may be useful as a related system reference.
Always confirm the old sensor label, system manual, control board connection, and cable route before ordering. Similar-looking temperature sensors may not have the same resistance rating, cable length, or connector style.
When to Replace the Temperature Sensor
This sensor may need replacement if the system shows incorrect water, air, or solar temperature readings. It may also be needed if the cable is cut, the sensor is corroded, the clamp is damaged, or the reading does not change after normal troubleshooting.
A faulty sensor can affect displayed temperature information, but it should not be confused with salt cell failure, flow switch failure, or main control board issues.
Installation Guidance
Turn off power to the pool equipment before removing or installing the sensor. Route the 15-foot cable carefully so it does not touch hot surfaces, sharp edges, moving equipment, or high-voltage wiring.
Install the sensor in the correct location based on whether it is being used for water, air, or solar temperature sensing. Make sure the sensor is secured properly and the cable connection is clean and fully seated.
If the control board connection is damaged or the system still does not read correctly after sensor replacement, the Hayward GLX-PCB-RITE replacement main PCB may need to be inspected separately.
Testing and Troubleshooting Tips
After installation, restart the system and check whether the temperature reading appears normal. Allow the system a little time to stabilize before assuming the reading is incorrect.
For saltwater pool maintenance, temperature is only one part of system troubleshooting. Salt level should also be checked with a reliable meter such as the Hayward GLX-SALTMETER digital handheld salt meter.
If salt readings seem inconsistent during service, the Hayward GLX-CAL-SOL 3200 PPM salt meter calibration solution may help verify salt meter accuracy before adding more salt.
Related Sensor Parts
Temperature sensors and flow sensors serve different purposes. If your system is showing “No Flow” or flow-related warnings instead of temperature problems, the Hayward GLX-FLO-RP 15 cable flow switch may be the related part to review.
Maintenance and Care
Inspect the sensor cable during seasonal startup and regular equipment checks. Replace the sensor if the cable jacket is cracked, the sensor body is damaged, the connector is corroded, or the readings remain inaccurate after checking system settings.
Do not pull the cable sharply or force the connector into the control board. Keep the sensor and cable away from chemical spills, standing water, and areas where the cable can be pinched.
