Mitsubishi MS-A09WA-1 Thermistor
A very basic thermistor is a certain type of resistor that has a fluctuating resistance that is directly proportioned to heat. They tell the system when a temperature in increasing or decreasing. The HVAC system takes the temperature in order to make a decision on what needs to be done.

- The whole system may not even begin to function because of any thermistor that is damaged
