Aqua Rite Thermistor Test Procedure?

A faulty thermistor in a Hayward Aquarite system can be identified by the absence of power and chlorinating light, or no power to the salt cell. This is a critical issue that can be fixed using a soldering iron and a new thermistor. To troubleshoot the system, check the correct salt cell size and apply a heat source while holding the multimeter on the thermistor’s legs.

If the system stops producing chlorine, shows 0 ppm salt, 0 sanity, and 0 amps, and shows no signs of power, it may need to be replaced. Check the voltage and pull the fuse out if necessary. If the No Flow LED flashes, wait 60 seconds after starting the pump and filter. Check for possible turbulence or obstructions inside the flow tube. Verify the salt level is 2700-3400ppm and check with an independent test to ensure accuracy.

The process is easy to test, as it requires removing the front cover to access the motherboard. The thermistor is a critical component in the AquaRite Hayward Chlorinator, and a new one can be easily installed.
