LG ARNU073TJC2 Limit Switch
The limit switch has a sensor located in the furnace that can determine if and when the air is warm enough for the blower to be activated. One big reason why limit switches are designed that way is due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
How do you know when your limit switch is about to go out?
- The HVAC system is beginning to erratically more often than not
- The HVAC system will not begin or will not stay running as it should
