With a 2 Ohm resistance at ambient temperature and a steady-state current capacity of 25 Amperes, it effectively limits startup current and safeguards your equipment. Compact and easy to install, it’s a cost-efficient replacement part favored by both professionals and savvy DIYers to extend the life of their pool systems. ## Description Ametherm SL32 2R025 High-Energy Thermistor For HAYWARD / GOLDLINE / AQUA-RITE GLX-PCB-RITE (Can replace AS32 2R025) This board failure is often due to the "sacrificial" destruction of the thermistor used to protect the circuit from high voltage and high current surges that could occur after a lighting strike during thunderstorms or other power surge. Normally the thermistor protects the circuit on start-up, providing a relatively high resistance (2 Ohm) at ambient temperature to limit "InRush Current", and then essentially disappearing from the circuit (0.02 ohm) when the current is near or equal the design current of 25 Amp. The part will fail when a power surge is much greater than the power handling capability of the part. The correct replacement thermistor is: Ametherm ICL - SL32 2R025 High Energy Dissipation without Failure Inrush Current Limiting (ICL) Thermistor (1 Thermistor) (Inrush Current Limiting Thermistors) (Use to repair: Hayward Aqua Rite PCB (GLX-PCB-RITE) Pool Chlorinator) Note: Either AS32 2R025 or SL32 2R025 may be used , but the AS Thermistor will protect against a higher energy surge. ICLs (Inrush Current Limiters) are a cost-effective way of limiting the inrush of current that can damage other components in a switching power supply and other devices when the equipment is turned on.

Lead Length: 38 mm (1.5 inches) Review: Not TOO difficult to install - Like the other reviewers, my Aqua Rite Goldline AQR salt chlorine generator stopped working. Both the "power" and the "generating" lights wouldn't light up. I tested the fuse and ensured power was available to the panel first. Even though it had power, the top two indicator lights (the power and generating lights) wouldn't illuminate. Also, my pool had no chlorine and turned green. I figured I'd try to replace the thermistor (like I saw on YouTube and read in the comments here). While I'm generally pretty handy, I don't know anything about replacing electronic components from a circuit board. I watched a couple videos on YouTube on soldering and desoldering and purchased a cheap soldering iron and some solder. After removing the circuit board (easy -- the wires are color-coded and the board is well-marked (take a couple pictures just in case)), I gave it a shot. It took about 15 minutes total to remove and replace the thermistor. It really wasn't too hard. I reinstalled the circuit board and turned the power back on and everything worked. The power and generator lights lit. Best of all (of course), my green pool is back to being blue and clean. I don't know how long this new thermistor will last (the original only made it about 4 years), but if it dies too, I guess I'll just keep replacing until the whole circuit board dies. I'm really glad I gave this a try. I saved quite a bit of money and now I know that I can fix this problem if it happens again. Review: Worked like a charm!!!!! - So like many other reviews here.....I bought the part. Not knowing, but was pretty certain it was the problem. The front of the board did not look discolored or burnt. The piece itself did not look bad or even cracked. However we took off the old piece and put the new on one. If your not sure how to solder, I would suggest a you tube video and also buy desoldering wick remover (buy that on desertcart) as I was not able to find anyone local who carried it. Radio shack would be a great choice, but ours was not longer in business here. We went ahead and installed the new piece and soldered it back to the board, front side and back side. Put the boards back into their places, hooked all the wire back up, and turned the power on..... WE HAD POWER AND GENERATING SALT AGAIN!!!!!! The original piece when I picked it up and put into my hands, I noticed several hairline cracks. I put just a tad bit of pressure and the whole things crumbled right there. I posted pics with this review and hope it helps. Saved us $350 for the new board!!!! Spent $11.60 for this piece. ## Features - Aqua-Rite Repair Kit Themistor, SL32 2R025 - Can Replace: AS32 2R025 ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 156 Reviews | ## Images ![AMETHERM SL32 2R025 NTC THERMISTOR by Ametherm - Image 1](https://m.media-amazon.com/images/I/61kIgBl2WcL.jpg) ![AMETHERM SL32 2R025 NTC THERMISTOR by Ametherm - Image 2](https://m.media-amazon.com/images/I/61e6cDPChBL.jpg) ![AMETHERM SL32 2R025 NTC THERMISTOR by Ametherm - Image 3](https://m.media-amazon.com/images/I/517XGQaVWAL.jpg) ## Questions & Answers **Q: can i replace sl32 2r025 with a AS model** A: Yes - but the AS has different, heavier, leads (may not fit PCB holes) and is designed to take greater power surge before sacrificially failing. The AS was designed with same ambient resistance and same very low resistance at 25A as the SL version. Circuit function is identical. Supposedly fails less often after huge power spikes like lightning strikes. (And more expensive.) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not TOO difficult to install *by A***R on September 24, 2014* Like the other reviewers, my Aqua Rite Goldline AQR salt chlorine generator stopped working.

I was on my second board already and it lasted only 3 seasons. Rather than spend $400 on another board, I tried this ~5$ fix first. I attempted to remove the old thermistor by heating the solder points with my iron and trying to pull out the wires. I could not get the existing solder to melt and ended up breaking the old thermistor apart. From there, I trimmed the wires as close to the board as possible and drilled new holes in the board to mount the new thermistor. The new holes worked great and I soldered everything up and installed the board. Everything worked and i have a spare thermistor for the inevitable failure again in a few years. ## Frequently Bought Together - AMETHERM SL32 2R025 NTC THERMISTOR by Ametherm - Ametherm SL32 2R025 (Pack of 2) Aqua-Rite Thermistor, ICL 2 OHM 20% 25A 30MM --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/37875846-ametherm-sl32-2r025-ntc-thermistor-by-ametherm](https://www.desertcart.tn/products/37875846-ametherm-sl32-2r025-ntc-thermistor-by-ametherm) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-03*
