it did the job and saved me from having to buy a new heater

### ⭐⭐⭐⭐⭐ 







  
  
    Easy Install and Great Product
  

*by R***N on Reviewed in the United States on 8 April 2022*

My temperature on my Pentair Mastertemp HD 400 was reading 126 and the unit would not fire up because the max temp is 104.  Go on you tube and watch the installation video, very quick and easy.  The part worked like a charm, took 10 minutes to install.  Works great!

### ⭐⭐⭐⭐⭐

*by C***R on Reviewed in Australia on 18 January 2020*

Temperature was a reading wrong as in way too high on my Pentair 4000HD. This fixed it by replacing the sensor
