When a thermistor fails or drifts, the heater can show incorrect temperatures, overshoot or undershoot your set point, or post sensor faults. This genuine Pentair replacement restores accurate readings so your heater or heat pump can control water temperature correctly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e⚠️ Important Purchase Notice\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis listing is for the thermistor probe only.
