Carrier 48GP Thermistor
In an HVAC system, a thermistor is a specific kind of resistor whose rated resistance is directly proportioned to heat. They notify the circuit board when a temperature has been reached. The heating and cooling system needs to know the temperature in order to understand what is going on.
How do you know if your system thermister is not working right?
- The initial sequence may not function depending on which is the broken thermistor
- Blower fan could refuse to begin to ramp up to full speed
