Mitsubishi MSZ-A17NA Thermistor
A very basic thermistor is a specific kind of resistor that has a fluctuating resistance that is solely dependent on the amount of, or lack thereof, heat. They tell the system control board when the temperature has been reached. The control board deciphers the temp in certain areas to make a decision on what needs to be done.
Major warnings of a laboring Mitsubishi thermister
- The whole HVAC system may not even begin to function depending on which is the stuck thermistor
- The blower refuses to begin to engage full speed spinning
