International Comfort Products CAC436AKA1 Thermistor
A thermistor is a type of resistor which has a resistance that fluctuates depending on the temperature. The heating system must know the temp throughout the whole system to do its job as it should. They can tell the system when a temperature reaches a certain point.
What signals that my all-important thermister is almost going bad?
- The main blower refuses in its attempt to begin full speed blowing
- The entire system could possibly never start due to any one damaged thermistor
