International Comfort Products MF20N2600A1 Thermistor
A very basic thermistor is a specific kind of resistor whose resistance is dependent on the heat. The HVAC system reads the temperature in certain areas to be sure everything is going well. They inform the HVAC system when a certain temperature reaches a certain point.
Red flags your all-important thermister should need replacing
- Main blower may refuse in its attempt to get up to full speed
- The heating and cooling system may not initiate the starting sequence because of any broken thermistor
