Carrier 50JZ024300 Thermistor
In an HVAC system, a thermistor is a specific kind of resistor that has a fluctuating resistance that is directly proportioned to temperature. The control board needs to know the temperature in order to make sure everything is running smoothly. They notify the system control board when the temperature has been reached.
Some warnings your thermister needs replacing
- The blower may refuse to begin to ramp up to full speed
- No component may not even begin to function because of the stuck thermistor

If you are going to be buying or purchasing, do your due diligence and make sure of the correct model as well as make a visual comparison so that you are positive that the correct replacement thermistor is being ordered. There is no need to install the replacement part alone. Hire a pro locally to do the job for you.
