International Comfort Products T8MPN150J20A1 Thermistor
In an HVAC system, a thermistor is a specific kind of resistor whose rated resistance fluctuates depending on the current temperature. They tell the circuit board when a certain temperature has been reached. The system control board deciphers the temp in a few critical areas to ensure that things are as they should be.
What warnings are present when my International Comfort Products thermister is on its last leg?
- The initial sequence may not even begin to function because of the failed thermistor
- Main blower may fail in the attempt to engage full speed
