Weil-mclain wm383700321 Display Board Assembly for Eco Tec Model 80 110 150 and 199 Gas-fired Water Boilers

Product Description

The Weil-McLain wm383700321 Display Board Assembly is a direct replacement control component designed for use with ECO Tec Model 80, 110, 150, and 199 gas-fired water boilers. This display board serves as the primary user interface on the boiler unit, allowing technicians and homeowners to monitor system status, view diagnostic codes, and adjust operational settings. Weil-McLain is a well-established name in the hydronic heating industry, and this assembly is built to meet the exacting standards required for reliable residential and light commercial boiler operation.

The display board assembly integrates with the boiler control system to communicate real-time data about the heating cycle, water temperature, error conditions, and operational modes. When a display board fails or becomes damaged, the boiler loses its ability to communicate system status clearly, making troubleshooting difficult and potentially leaving the system running without proper user feedback. Replacing the faulty board with a genuine OEM part like the wm383700321 restores full display functionality and ensures compatibility with the existing control architecture of the ECO Tec boiler series.

HVAC technicians working on Weil-McLain ECO Tec boilers will recognize this part as a critical component in maintaining system diagnostics and user control. The assembly is matched specifically to the ECO Tec platform, so fitment and electrical compatibility are assured when used on the correct models. Using an OEM display board eliminates the guesswork that comes with third-party alternatives and supports the long-term performance of the heating system. This part is a go-to solution for service calls involving blank displays, flickering screens, or unresponsive boiler interfaces on any of the four compatible ECO Tec models.
