International Comfort Products T2A336GKA100 Thermistor
In an HVAC system, a thermistor is a specific kind of resistor whose resistance fluctuates depending on the amount of, or lack thereof, heat. They can tell the system when a certain temperature in increasing or decreasing. The main control board deciphers the temp in some specific areas of the system to make a decision on what needs to be done.
What warnings should I watch out for to know if my thermister needs replacing?
- The system blower may refuse to begin to begin full speed blowing
- The system may not function due to any one thermistor that is damaged
