Lennox 98G46 Auto Limit Switch 100°F-140°F

The Lennox 98G46 is an auto limit switch, which is a safety device for many HVAC equipment such as furnaces, air handlers. It protects the system as it will shut it down if the temperature of the air that goes inside the unit is high so to avoid any harm. The switch also measures the air temperature inside the unit. If the temperature goes beyond the already programmed range, which is normally between 100°F and 140°F, the switch triggers a shutdown to protect the system from overheating. This safety measure assists in the prevention of premature wear of your HVAC equipment and its proper functionality.
