International Comfort Products T8MPL100J20A1 Thermistor
In an HVAC system, a thermistor is a type of resistor whose resistance is solely dependent on the amount of, or lack thereof, heat. They convey to the system control board when the temperature has been reached. The heating system deciphers the temp in several different areas to understand what is going on.
Key signs to watch for in a bad temp regulating thermister
- The AC and heat system may not initiate the starting sequence because of the malfunctioning thermistor
- The main blower may fail to begin to ramp up the airflow
