Heat Controller B-VMH18FC-1 Thermistor
A very basic thermistor is a type of resistor that has a varied resistance that is directly proportioned to the amount of, or lack thereof, heat. They tell the main board when a temperature has been reached. The system reads the temperature in order to do its job as it should.
Signals your all-important thermister should need replacing
- The whole HVAC system could never start up due to a thermistor that is malfunctioning
- The system blower could never begin in its attempt to ramp up to full speed
