Customer Questions and Answers for Controller Assembly (Main Electronic Control) by Lg

This controller assembly is the appliance's main electronic control that manages cycles and user inputs to restore proper control operation. Replace a failing controller assembly to address unresponsive controls, incorrect cycle behavior, or intermittent errors. What it does:

• Manages cycle selection, timing, and communication between sensors and motors to coordinate appliance operation.
• Interprets user inputs from the front panel and sends commands to other components.
• Failure may cause unresponsive buttons, unexpected error codes, stalled or incorrect cycles, or an appliance that won't start.
• Replacing the assembly often resolves control-board–related faults when diagnostics point to the main controller.

• Disconnect power (unplug or switch off breaker) before removing the old assembly to avoid shock or damage.
• Handle the board and connectors carefully; avoid static discharge and cradle the assembly by its edges.
• Match the replacement to the exact part number and transfer any brackets, grounding straps, or button housings as needed.
