Samsung AM18A1C09 Thermistor
In an HVAC system, a thermistor is a specific kind of resistor which has a resistance that is altered by the amount of, or lack thereof, heat. They tell the HVAC system when the temperature has been reached. The heating system reads the temperature in a few critical areas to do its job correctly.
Symptoms of an ailing all-important thermister
- Primary blower refuses in the attempt to engage full speed spinning
- The heating and AC system may never begin due to a bad thermistor
