This aftermarket replacement for the Pentair® 471566 Heat Pump & Heater Thermistor Probe is a common replacement part for your Pentair® MiniMax® pool heater. Often times your probe will need to be replaced when your heater is displaying error code "E02", or displaying "HI" and your heater will not turn on.

Great product at an even greater price.

Great service, best price and

Great service, best price and part arrived well before normal. After I ordered I checked the web only to find a claim that this company is a fraud and to stay away from ever using them --- Not my experience! I highly recommend PoolGuySupply based on my experience.

The part fit and works perfectly. My Pentair NT is back heating the water.

Thank you.
