Carrier KFCEH1101C10 Thermistor
In an HVAC system, a thermistor is a type of resistor whose rated resistance is altered by temperature at its location. The heating and cooling system must know the temp in certain areas to ensure that things are as they should be. They can tell the system when a certain temperature has been reached.
Major warnings your all-important thermister has very little life left
- The main blower may fail to begin to ramp up to full speed
- The whole system could possibly not even begin because of any thermistor that is stuck open
