Lennox 36W90 160-190F Auto Limit Switch

The Lennox 36W90 is a Auto Limit Switch with 160-190F, an essential safety device in HVAC systems especially in furnaces. This product is used to regulate the temperature of the heating unit and it measures the temperature, and switches on or off the heating element when necessary. It is particularly designed to operate at temperature of 160°F to 190°F, to guarantee that the furnace does not exceed acceptable temperature limits. When temperatures increase more than the upper limit it looks for a switch that can shut down the power supply for the heating element to avoid system damage.
