Carrier 38EYG036 Thermistor
A thermistor is a special kind of new age resistor whose rated resistance is governed by temperature. They can tell the circuit board when a temperature reaches a certain point. The furnace or AC must know the temp in order to make a decision on what needs to be done.
What are some indications that my system thermister is about to go out?
- Blower motor refuses in its attempt to ramp up
- The AC and heat system may never begin due to a thermistor that is malfunctioning
