Carrier 38HDF018 Thermistor
A thermistor is a specific kind of resistor that has a varied resistance that changes as it depends on current temperature. They notify the circuit board when a certain temperature reaches a certain point. The control board needs to know the temperature in a few critical areas to know what to do next.
What happens when my Carrier thermister really needs to be replaced?
- The system blower could fail in the attempt to ramp up to full speed
- The heating and AC system could possibly not even begin because of any bad thermistor

If you decide on picking up or ordering do your best and double check the model number and also make a visual inspection so that you are positive that the proper replacement thermistor is the one being purchased. If you are unsure about installing the new thermistor by yourself then it may be wise to find a professional in your area to do the replacement of the part.
