SL32 2R025 (Pack of 2) Aqua-Rite Thermistor, ICL 2 OHM 20% 25A 30MM

Used this part as so many do to fix my Aquarite salt generator. I did this repair once many many years ago as I have been using the Aquarite units since my pool was installed in 1999. This is not the original Aquarite. It’s been replaced at least once as I recall.What was strange this time was when I opened the unit the thermistor (this part) was disconnected from its solder joints as if someone had “snipped” the connecting wires right at the solder joints at the board. The thermistor was just laying there on top of another component loose as of it had just fallen to that point. It was not falling apart or burnt looking.So I simply soldered the existing thermistor back to the board and thought it was fixed. Indeed it appeared fixed at first since the led lights were then working to indicate power and generation of chlorine.Unfortunately the next day the lights were off again and I found the thermistor in exactly the same spot as before - laying on another component below where it was supposed to be soldered in. Again the solder joints had failed.Fortunately I had ordered this thermistor 2 pack the day before because I wasn’t sure that the thermistor I had simply soldered back was actually good. Even though I was originally hopeful when the lights came on at first. But I knew it was old. Maybe 7 to 10 years?So I soldered one of the new thermistors in after shortening the leads a bit. The originally leads are so long I was concerned the thermistor may contact the front plate if left that long. But I only removed 1/4 inch or so. The unit is again working and time will tell if the thermistor falls off again.My theory is the thermistor had gone bad and was perhaps super heating causing the solder joints to melt. Perhaps the short leads contributed to that as well. I had read somewhere to ensure the leads were somewhat long so the thermistor body wasn’t too close to the board as it get hot. Like 400 degrees hot!If this doesn’t work I’ll have to buy a whole new board.I hope this info helps someone.Update: it’s been almost a week now and the new thermistor has not fallen off or failed. I believe the old one was defective and this is just what was needed to fix the unit. This saved a substantial amount of money over a whole new board or box! It does also demonstrate that we’ve become a society of “toss and replace” however with nothing being fixed anymore. I say that because this thermistor repair is not something your local pool service company would offer as an option. They would only replace the entire board at a cost of several hundred dollars!

Thought I needed to replace my whole unit, but this little bugger made the salt system computer come back to life! I didn’t even use solder. I joined the old solder legs (I left them about 1/2” long) with inline connectors for electrical wiring. Worked great, so cheap and I have a spare!

after 15+ years the thermistor went bad and the chlorinator behaved erratically, on a few seconds and then the indicator LEDs shut off. research on Amazon and found this "popular" item being purchased often and the description matches with my dead chlorinator behavior. located the component inside AdquaRite box. a slight pull and the old thermistor just crumbled to pieces!! my soldering iron was out of order. so i just picked up the smallest heat shrink tube 3/32" for $2 at HD. trim the wires to proper length then squeeze in the two wires in the tubing to make the connections. now the chlorinator is back generating chlorine. $10 for the fix and no need to replace the expensive boards

I was able to fix our aqua rite salt generator using this part and saved $250 or so. You need a powerful soldering iron to remove the old part. I did not see any obvious defects in the original thermistor nor did I see any obvious burn marks on the PCB. I did test for continuity between the two ends of the thermistor on the board and there was no continuity. Removal was straight forward and once installed the generator was up and running in 20 minutes. This thermistor seems to be less substantial than the original, thinner and lighter. But it has been operating for two months now with no issues.

Fixed my pool salt converter.

Exact fit

After discovering my Swimpure Plus wasn’t generating, I searched for replacement units and stumbled upon these in the search results. I didn’t even bother checking to see if that’s what actually failed, it seems to be a common failure and it was cheap enough to try. Worked perfectly. Yes, they do get very hot.

Replaced my thermistor for Aquarite board when original part stopped working. Easy to solder on the board. One thing to remember is that original thermistor has a high temp solder as the board gets hot after a few hours. So do not use a low temp solder. If unsure, cut the legs of old thermistor 1cm above the board and solder the new one to this legs.
