International Comfort Products PGAA30D1K6 Thermistor
In an HVAC system, a thermistor is a specific kind of resistor whose resistance is altered by temperature at its location. The HVAC system needs to know the temperature in several different areas to be sure everything is going well. They inform the main board when a certain temperature in increasing or decreasing.
Major clues of a weakening system thermister
- The system blower refuses to begin to ramp up to full speed
- The whole HVAC system may not initiate the starting sequence due to a improperly set thermistor
