Carrier 50TM004 Thermistor
A thermistor is a type of resistor that has a fluctuating resistance that depends on the temperature at its location. The heating and cooling system needs to know the temperature throughout the whole system to do its job as it should. They notify the HVAC system when a certain temperature reaches a certain point.
What are the clues to watch out for to know my Carrier thermister is about to stop working?
- The system may not even begin to function due to any one thermistor that has failed
- The blower refuses in its attempt to engage full speed

Before you decide on buying or purchasing, do your due diligence and cross-check the correct model and also make a visual inspection so that you are positive that the correct thermistor is the one being purchased. If you are unsure about the properly replacing the new thermistor by yourself then it is probably best to consult a pro to do the replacement of the part.
