Carrier 25HPA436A0030010 Thermistor
A very basic thermistor is a specific kind of resistor whose rated resistance is directly proportioned to temperature at its location. They can tell the heating and cooling system when a certain temperature has been reached. The main control board interprets the temperature in some specific areas of the system to do its job correctly.
What are the clues to watch out for to know my Carrier thermister is failing?
- The AC and heat system could possibly not operate due to a thermistor that is the problematic one
- Primary blower fails in its attempt to ramp up
