International Comfort Products N9MP2125J20C1 Thermistor
In an HVAC system, a thermistor is a thermal resistor, whose rated resistance fluctuates depending on the temperature. The system must know the temp in several different areas to know what to do next. They can tell the main board when a temperature has been reached.
Easy warnings your thermister is going out
- The heating and cooling system may not function depending on which is the inaccurate thermistor
- The blower fails in its attempt to get up to full speed
