International Comfort Products CAC036AKA1 Thermistor
In an HVAC system, a thermistor is a specific kind of resistor that has a varied resistance that is directly proportioned to the amount of, or lack thereof, heat. The main control board deciphers the temp in order to ensure that things are as they should be. They tell the circuit board when the temperature reaches a certain point.
Clues to watch for to know your thermister will not last the year
- The heating and AC system could possibly not operate because of the improperly set thermistor
- The blower refuses in its attempt to engage full speed
