The 3-way valve harness is a dedicated wiring set that connects the 3-way diverter valve to the boiler's control board. This valve directs water flow between heating and hot water circuits, and the harness ensures precise electrical control for smooth switching. If the harness is faulty, the valve may not operate correctly, causing temperature issues or system errors. Replacing this harness is a typical part of boiler maintenance and repair, helping to maintain efficient operation of your heating system.
