I saved a bunch of money not having to get a service call and the additional markup. Easy to install if you are handy. Review: Fixed my Pool Heater Myself - My Pentair Mini-Max NT was acting up not too long ago. It wouldn't come on to heat the spa or pool as the temperature it was reading was way too high. I didn't know for sure what was wrong with my heater, but had a hunch that maybe the thermistor probe had gone bad. Since I figured it wouldn't hurt anything if I replaced the probe and was wrong, and since it's a pretty cheap part, I decided to replace it. Turned out It was pretty easy to replace the probe once I was able to get the main heater cover off. (Getting the cover off, however, was a PITA). Just took out the old one with a wrench, cleaned off the hole and threads, and replaced new one with some Teflon tape. My heater now works like new. ## Features - Thermistor Probe, Pentair Minimax NT - 471566Z ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #379,373 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #496 in Swimming Pool Heater Parts | | Customer Reviews | 4.7 out of 5 stars 353 Reviews | ## Images ![Thermistor Probe, Pentair Minimax NT - Image 1](https://m.media-amazon.com/images/I/6128nA8iU3L.jpg) ![Thermistor Probe, Pentair Minimax NT - Image 2](https://m.media-amazon.com/images/I/512vxT2534L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked perfectly *by J***R on March 18, 2024* Excellent.

Manual says contact service tech but further research said it's normally the thermistor. If it wasn't that it would most likely the control panel circuit board which goes for around $400. Cheap part for troubleshooting and super easy to install. Fixed the problem. Just note it didn't come with plumbers tape but I always have some at the house. ## Frequently Bought Together - Pentair 471566 Thermistor Probe Replacement Pool/Spa Pump and Heater - Pentair 473605 Water Pressure Switch Replacement Pool and Spa Heat Pump - Pentair 471694 150-Degrees Fahrenheit Hi-Limit Thermostat Replacement MiniMax Pool and Spa Heater --- ## 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.nz/products/12740640-thermistor-probe-pentair-minimax-nt](https://www.desertcart.nz/products/12740640-thermistor-probe-pentair-minimax-nt) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-08-13*
