Description
The Weil McLain 591-391-850 Burner Harness Assembly is an electrical connection component used to transmit power, and control signals between burner-related sections within heating equipment and HVAC systems. It is applied in boiler applications where stable electrical communication is required for ignition sequencing and coordinated burner operation. It helps connect control boards, ignition components, and related electrical sections to support consistent system performance. Installed as part of the burner control circuit, it contributes to signal transfer, operational continuity, and proper interaction between heating and control operations.
