I need to replace Thermistor in my Sta-Rite Gas pool heater. Can you help how
Hi Moliner, We do not have installation instructions on how to replace the Thermistor. I would recommend consulting a pool professional to have this item replace if you're not sure on how to replace it.
Less than 1 hr
Screwdriver, Socket Set, punch
I ran through troubleshooting in manual, that did not cover the problem. Then I realized the number 126 was what the heater thought the water temp was, and did not think it needed to ignite.
In removing the old thermister, I found that it had corroded and the new one did not fit. This necessitated removing the manifold with 6 bolts, and clearing the hole. Then it fit. Reassembled, "We have ignition". Nothing complex. I used a small punch to scrape the corrosion. Less than 45 minutes total.
(5 out of 5 stars) No one local carried this...but INYO does!

After searching at every pool store in our area and no one carried this thermostat for our pool heater, I remembered to check with INYO. Of course, INYO had it in stock. Thank you!
