Nordyne M1M Thermistor
In an HVAC system, a thermistor is a thermal resistor, whose resistance fluctuates depending on the current temperature. They notify the circuit board when a temperature reaches a certain point. The control board deciphers the temp in certain areas to understand what is going on.
What are some hints that my all-important thermister is on its last leg?
- Blower fan could refuse to begin to engage full speed
- The initial sequence may not function due to any one thermistor that is damaged
