Tripp Lite SRCOOL12K Thermistor
In an HVAC system, a thermistor is a thermal resistor, whose resistance is directly proportioned to the amount of, or lack thereof, heat. They inform the circuit board when the temperature reaches a certain point. The HVAC system deciphers the temp in some specific areas of the system to do its job correctly.
General indicators that your your all-important thermister will soon need to be replaced
- The entire system could possibly not operate because of the thermistor that is damaged
- Blower motor refuses to begin to get up to full speed
