International Comfort Products TNE050B12G1 Thermistor
In an HVAC system, a thermistor is a specific kind of resistor that has a fluctuating resistance that depends on the current temperature. The control board reads the temperature in a few critical areas to ensure that things are as they should be. They can tell the circuit board when the temperature has been reached.
Clues your all-important thermister will need replacing
- The entire system could possibly not operate due to any one improperly set thermistor
- The main blower refuses in the attempt to ramp up
