International Comfort Products EF08B1500A1 Thermistor
A thermistor is a certain type of resistor whose resistance is altered by temperature. They can tell the main board when a temperature has been reached. The HVAC system interprets the temperature in a few critical areas to be sure everything is going well.
What warnings should I watch out for to know if my main thermister is not working right?
- The blower may fail in the attempt to get up to full speed
- No component may not operate because of any thermistor that is stuck open
