Carrier 38YCC048 Thermistor
A very basic thermistor is a certain type of resistor that has a fluctuating resistance that is solely dependent on temperature. They can tell the main board when a certain temperature reaches a certain point. The heating system needs to know the temperature throughout the whole system to make a decision on what needs to be done.
What signals that my main thermister is in need of a replacement?
- The blower fails to begin to ramp up
- The initial sequence may never start up due to any one inaccurate thermistor
