Description
The Carrier HH680405 is an essential safety part referred to as an automatic limit switch for Carrier HVAC products. This automatic switch is useful in protecting your system from overheating especially in applications such as furnaces. If the temperature goes high, above a set point that is adjustable between 30°F and 250°F, the switch opens and breaks the circuit and thus the flow of electricity to the heating element. It protects your system by turning off the heating element when the temperature gets high, which can cause equipment damage and fire. In this way, the switch ensures the safe and proper functioning of your furnace and also increases its life.
