Know before you buy
This sensor acts as a safety cutoff switch that triggers at 150 degrees Fahrenheit. It is designed to prevent your pool heater from overheating, which protects the internal components from damage.
No, this specific part is engineered exclusively for the Pentair MiniMax NT and MiniMax CH heater models. Please verify your heater model before purchasing to ensure a proper fit.
Choosing a genuine OEM part ensures the sensor meets Pentair’s exact specifications for calibration and safety. Aftermarket parts may not trigger at the precise 150-degree threshold, which could compromise the safety of your heating system.
If your heater is shutting down prematurely or failing to fire despite the water being below the set temperature, the sensor may be faulty. A malfunctioning sensor often fails to reset or provides incorrect temperature readings to the control board.
The installation is straightforward for those comfortable with basic pool heater maintenance, as it is a direct-fit replacement. However, always ensure the power to the heater is completely disconnected before attempting any repairs.
