Lennox 23G38 Auto Limit Switch L180F-40F

The Lennox 23G38 Auto Limit Switch is an integral part of safety control in many HVAC equipment such as furnaces and air handlers. It acts as an anti-heat check mechanism to keep the system safe from high heat should the event arise. Temperature is also sensed, and the electric circuit is disrupted when its value goes beyond the optimum range, which ranges from 180°F (82°C) to 40°F (4°C). It has the capacity of making a significant impact on the safe and optimum functionality of the HVAC systems installed in most homes today.
