This specific model is primarily utilized as a chiller liquid solenoid

System Reliability: Ensures the pressure switch closes consistently by maintaining a steady vacuum

Optimized Signal Distribution: Restores proper communication between the ICB (Integrated Control Board) and fan motors or gas valves

Its steatite insulator and zinc-plated steel mounting tabs provide the physical stability required to withstand the mechanical vibrations of industrial gas burners

Carrier LH680003 Pilot Assembly 320788-704 This specific model is primarilyThe Carrier LH680003 Pilot Assembly is a critical OEM replacement component designed for high reliability intermittent pilot ignition in specific Carrier, Bryant, and Payne gas fired furnaces and water heaters. As a veteran grade three wire pilot assembly, this unit integrates both the ignition source and the flame sensing mechanism required to prove the pilot flame before the main burner gas valve is authorized to open. In these legacy systems, the
