Carrier 50JZ-A Thermistor
A thermistor is a thermal resistor, whose resistance is altered by temperature at its location. They inform the main board when the temperature reaches a certain point. The system interprets the temperature in certain areas to do its job as it should.
Key indicators that my Carrier thermister is in need of replacing?
- The blower could never begin in its attempt to ramp up to full speed
- The initial sequence may never start up because of the thermistor that is damaged
