International Comfort Products PGME48G1355 Thermistor
In an HVAC system, a thermistor is a special kind of new age resistor whose rated resistance varies depending on the current temperature. They notify the heating and cooling system when the temperature reaches a certain point. The furnace or AC deciphers the temp in a few critical areas to make sure everything is running smoothly.
What are some indications that my all-important thermister is dying?
- The whole HVAC system could possibly never start due to any one improperly set thermistor
- The system blower could possibly fail to begin to begin full speed blowing
