Carrier 38TSA048 Thermistor

In an HVAC system, a thermistor is a certain type of resistor whose resistance fluctuates depending on the amount of, or lack thereof, heat. The system interprets the temperature in a few critical areas to do its job correctly. They tell the system when the temperature has been reached.

Check eBay to see if your thermistor is in stock!

If you are going to be buying or purchasing do your best and cross-check the correct model as well as make a visual inspection in order to be sure the correct thermistor is being ordered. You do not need to replace the part all by yourself. Consult with a professional in your town or city to do the job for you.
