Carrier 42S Thermistor
A thermistor is a certain type of resistor that has a fluctuating resistance that is solely dependent on current temperature. They can tell the main board when a temperature has been reached. The heating and cooling system deciphers the temp in certain areas to understand what is going on.
Important hints the temp-regulating thermister will have to be replaced
- The system blower may fail in the attempt to engage full speed
- The AC and heat system may never begin because of the damaged thermistor

Before buying or ordering do your best and double check the correct model and also make a visual inspection in order to be sure the correct thermistor is the one being purchased. There is no rule that says you have to install the part by yourself. Look for a professional in your town or city to hire and install the part for you.
