Mitsubishi MUZ-GE18NA Thermistor
A thermistor is a special kind of new age resistor whose rated resistance varies depending on the thermal temperature. The control board must know the temp in some specific areas of the system to understand what is going on. They can tell the system control board when the temperature in increasing or decreasing.
Red flags of a poorly working thermister
- Primary blower could fail in the attempt to ramp up to full speed
- The AC and heat system could possibly not operate because of the improperly set thermistor
