Friedrich MW18Y3F Thermistor
In an HVAC system, a thermistor is a special kind of new age resistor that has a varied resistance that is solely dependent on temperature at its location. The control board takes the temperature in order to make a decision on what needs to be done. They tell the main board when a temperature reaches a certain point.
Major signs the Friedrich thermister will soon need to be replaced
- The entire system may not operate due to a thermistor that is malfunctioning
- The blower may fail to begin to engage full speed spinning
