International Comfort Products PHAD60N1K1 Thermistor
In an HVAC system, a thermistor is a certain type of resistor which has a resistance that is governed by the amount of, or lack thereof, heat. They tell the main board when the temperature in increasing or decreasing. The HVAC system deciphers the temp in order to ensure that things are as they should be.
What are the signs that the International Comfort Products thermister is crapping out?
- The heating and AC system may never start up because of any thermistor that has failed
- The blower could never begin in its attempt to ramp up
