Haier HR30D2VAR Thermistor
A very basic thermistor is a type of resistor which has a resistance that varies depending on the temperature. The HVAC system needs to know the temperature in order to make a decision on what needs to be done. They can tell the circuit board when the temperature has been reached.
Important clues of a bad system thermister
- Main blower may fail to begin to begin full speed blowing
- The AC and heat system may not operate because of the problematic thermistor
