The LiftMaster K‑VGH1011MDAAVDN E‑BOX ASSEMBLY (also referenced as VGH1011M, WMS) is an OEM replacement electronic enclosure designed to restore the control functionality of select LiftMaster operator systems that specify this exact part number. As the central control hub, the E‑BOX manages command inputs, motor operation, and safety/accessory interfaces so the operator performs to factory standards. Use this assembly as a direct swap for a damaged or non‑functional unit by matching the part number and configuration called out in your operator’s official parts list or service manual.
This replacement part is intended for professional service and field repairs. Installation requires disconnecting power, removing the existing enclosure, and mounting/connecting the new assembly per the manufacturer’s wiring diagrams and setup procedures; programming or re‑learning of limits and accessories may be required based on the operator model. For compliance and safe operation, follow UL 325 and local electrical codes and verify that monitored safety devices and photoelectric sensors are correctly integrated and tested. Because configurations can vary, always confirm compatibility with your operator’s serial label, parts breakdown, or LiftMaster technical support before ordering or installation.
