Mitsubishi MSZ-A12NA Thermistor
In an HVAC system, a thermistor is a specific kind of resistor whose rated resistance varies depending on the thermal temperature. The HVAC system must know the temp in several different areas to make a decision on what needs to be done. They inform the circuit board when the temperature reaches a certain point.
Key indicators that my system thermister is not working right?
- No component may not initiate the starting sequence because of any problematic thermistor
- Blower motor may fail in its attempt to engage full speed spinning
