Carrier 25HNA624A0030020 Thermistor
In an HVAC system, a thermistor is a specific kind of resistor which has a resistance that is governed by thermal temperature. They notify the heating and cooling system when a certain temperature has been reached. The main control board takes the temperature in a few critical areas to make a decision on what needs to be done.
How do you know when your all-important thermister really needs to be replaced?
- No component may never begin because of any improperly set thermistor
- The main blower refuses to begin to begin full speed blowing
