Lennox XC14 Thermistor
In an HVAC system, a thermistor is a thermal resistor, whose rated resistance fluctuates depending on the temperature at its location. They notify the main board when the temperature has been reached. The control board deciphers the temp in some specific areas of the system to be sure everything is going well.
What happens when my all-important thermister is about to stop working?
- Blower motor could refuse to begin to engage full speed spinning
- The initial sequence could possibly never start because of any thermistor that is malfunctioning

If you are going to be buying or ordering do your best and cross-check the model number as well as make a visual inspection in order to be sure the right thermistor is the one being purchased. You do not have to replace the part all by yourself. Pay a professional in your area to do it for you.
Feel free to download your manual for help.
