International Comfort Products PGME42G1155 Thermistor
In an HVAC system, a thermistor is a type of resistor whose resistance depends on the amount of, or lack thereof, heat. The HVAC system needs to know the temperature in some specific areas of the system to do its job correctly. They notify the system when the temperature in increasing or decreasing.
What are some hints that my thermister is about to go out?
- The entire system could possibly not operate depending on which is the problematic thermistor
- The main fan could refuse in its attempt to ramp up
