Carrier 38YCG048 Thermistor
A thermistor is a certain type of resistor whose resistance fluctuates depending on the temperature at its location. The heating system interprets the temperature in some specific areas of the system to ensure that things are as they should be. They can tell the circuit board when a temperature reaches a certain point.
What are some indications that my Carrier thermister has a need to be replaced?
- The whole system may not even begin to function depending on which is the bad thermistor
- Blower fan may refuse in its attempt to ramp up
