International Comfort Products TCA224AKA1 Thermistor
In an HVAC system, a thermistor is a type of resistor whose rated resistance will fluctuate depending on the temperature at its location. The main control board reads the temperature in a few critical areas to do its job correctly. They can tell the system when a certain temperature reaches a certain point.
Key indicators that my temp regulating thermister is dying?
- The entire system may not even begin to function depending on which is the stuck thermistor
- The system blower could fail to begin to ramp up

If you decide on picking up or ordering do your best and make sure of the correct model as well as make a visual comparison in order to be sure the proper replacement thermistor is being ordered. Some pros could be quite expensive to hire so it is best to shop around to find a good deal if money is a concern.
