When water or fluid temperature exceeds the set threshold, the high limit control interrupts the burner circuit or heating element, shutting down the heat source before damage or hazard can occur. This component is a critical safety control, typically installed by licensed plumbers, HVAC technicians, or hydronic heating specialists working on boilers and water heaters. It is a direct OEM-sourced part from Lochinvar.\u003c\/p\u003e\u003cp\u003eHigh limit controls of this type are found in residential and light commercial hot water boilers, indirect water heaters, and combination heating systems. The L100208172 is suited for applications where maintaining a safe upper temperature boundary is required by code or equipment design. It mounts within the appliance control circuit and operates automatically without manual intervention during normal system function.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInterrupts burner or heating circuit when fluid temperature exceeds the safe operating limit\u003c\/li\u003e\n\u003cli\u003eOEM part sourced directly from Lochinvar for reliable fit and function\u003c\/li\u003e\n\u003cli\u003eDesigned for automatic reset or manual reset operation typical of high limit safety controls\u003c\/li\u003e\n\u003cli\u003eCompatible with hydronic boiler and water heater control circuits\u003c\/li\u003e\n\u003cli\u003eCritical safety component for code-compliant installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement high limit control for Lochinvar boilers and water heating equipment.
