Lennox CBX26UH Thermistor
In an HVAC system, a thermistor is a certain type of resistor that has a fluctuating resistance that is altered by heat. They tell the heating and cooling system when the temperature reaches a certain point. The system control board interprets the temperature in some specific areas of the system to be sure everything is going well.

If you are going to be buying or purchasing, do your due diligence and make sure of the model number as well as make a visual inspection so that you are positive that the correct replacement thermistor is being ordered. HVAC pros may charge higher prices than others so you could call around to acquire the best rate if you do not want to pay too much.
