Lennox CB30U-51 Thermistor
In an HVAC system, a thermistor is a certain type of resistor which has a resistance that is solely dependent on temperature at its location. They notify the heating and cooling system when the temperature has been reached. The main control board deciphers the temp in several different areas to be sure everything is going well.
Major warnings of a dying Lennox thermister
- The system blower could possibly fail to begin to begin full speed blowing
- The whole system may never begin because of any stuck thermistor

If you are going to be buying or purchasing do your best and cross-check the model number as well as make a visual inspection so that you are positive that the right thermistor is being ordered. HVAC pros may charge higher prices than others so it is best to shop around to acquire the best rate if you do not want to pay too much.
