Trane 2TWR1030A1000AA Thermistor
A very basic thermistor is a thermal resistor, which has a resistance that is directly proportioned to the amount of, or lack thereof, heat. They can tell the main board when the temperature reaches a certain point. The heating system takes the temperature in several different areas to do its job correctly.
Key clues of a poorly working Trane thermister
- Main blower may fail to begin to get up to full speed
- The whole HVAC system may not even start because of any thermistor that is the problematic one
