Lennox G40DF-60C-110 Limit Switch
The limit switch is a switch in the heat exchanger that can determine when the air is warmed to a point for the main blower to kick in and circulate the air. This is important due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts.
What signals that my chief limit switch has to be replaced?
- The HVAC system will not even start or continue to run like it is supposed to
- The Lennox system is beginning to act weird more often than not
