Haier CPN14XH9 Thermistor
In an HVAC system, a thermistor is a type of resistor that has a fluctuating resistance that is contingent on the current temperature. The heating system interprets the temperature in order to understand what is going on. They convey to the circuit board when a temperature has been reached.
Subtle cues to watch for in a failing system thermister

- The AC and heat system could possibly not operate because of any thermistor that is the problematic one
