Lennox G61MPV-36C-090 Thermistor
A very basic thermistor is a thermal resistor, which has a resistance that is solely dependent on temperature. They inform the system control board when the temperature in increasing or decreasing. The main control board needs to know the temperature throughout the whole system to do its job correctly.
What are the signs that the all-important thermister needs replacing?
- Blower motor could never begin in the attempt to ramp up the airflow
- The AC and heat system may not even start due to a thermistor that is damaged
