Friedrich MW30C3G Thermistor
A very basic thermistor is a type of resistor that has a fluctuating resistance that fluctuates depending on the heat. The system control board deciphers the temp in certain areas to understand what is going on. They tell the main board when a certain temperature reaches a certain point.
Signs the system thermister is in dire need of a replacement
- The entire system may not operate because of the broken thermistor
- Blower motor could never begin in its attempt to ramp up
