Description
The York S1-02546422000 High Limit Control Snap Disc is a temperature-sensitive safety system used to monitor heat levels within heating sections in HVAC systems. Designed with a 130F limit and a 20F differential, it responds to rising temperatures by opening the electrical circuit when the set point is reached, then resetting after cooling. It is commonly placed near heat exchangers or electric heating elements in furnaces and air handlers. Within the system, it plays a essential role in avoiding overheating conditions and supporting controlled operation of heating components.
