Replaced this sensor in pool heat pump myself. Worked great and fixed issue with heater not working. Bought a second one in case needed again in future. Appears to be a common failure mode in heat pump.

Excellent. I saved a bunch of money not having to get a service call and the additional markup. Easy to install if you are handy.

Opted for Pentair brand. Probably could have gotten cheaper, but didn't want to risk

Heater hadn't been used for months and when we tried it didn't come on and had an Err message on the display and the Service light was on. 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.

Perfect fit. wires on this one are about a 26-28ga. wires on the original in my heater were 36ga, very thin and falling apart. Plus mice seem to like the thin gage wire, they chew it up and use it for nesting.Good quality, installed in a snap and fixed my issues with the heater not igniting. Fired right up after I installed it.

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.
