Goodman P1256801F Thermistor
In an HVAC system, a thermistor is a type of resistor whose rated resistance is governed by thermal temperature. The control board takes the temperature in certain areas to understand what is going on. They inform the circuit board when a temperature reaches a certain point.
What to see if the main thermister is on its last leg?
- The heating and cooling system may never start up because of any stuck thermistor
- Blower fan may fail to begin to get up to full speed
