Lennox G61MPV Thermistor
In an HVAC system, a thermistor is a type of resistor whose resistance changes as it depends on current temperature. They tell the system control board when the temperature reaches a certain point. The control board takes the temperature in several different areas to do its job correctly.
Warnings of a barely functioning Lennox thermister
- The heating and AC system may not even begin to function because of any problematic thermistor
