The negative temperature coefficient (NTC) thermistors consist of metals with resistance values that change predictably in response to changes in temperature (resistance increases as temperature decreases and vice versa). For that reason, we often use them as temperature sensors in a variety of equipment types. In our latest video, our commercial HVAC team talks all about thermistors and covers the common types, various applications, and troubleshooting. You can watch it on the HVAC School websi
