Whirlpool ATR1255CPP0 Thermistor
In an HVAC system, a thermistor is a type of resistor which has a resistance that is solely dependent on heat. The system control board needs to know the temperature in certain areas to ensure that things are as they should be. They notify the circuit board when the temperature reaches a certain point.
