Parts for Lg LDG3011ST: Controller Parts

This membrane is the flat control-panel keypad used to operate the appliance. It restores button responsiveness and protects the underlying electronics so your controls register commands reliably. What it does:

• Replaces a worn or damaged keypad membrane so button presses register correctly
• Restores normal control-panel input when buttons are unresponsive or intermittent
• Helps protect the control board from dirt, moisture and wear
• Works with the existing control assembly to send user commands to the appliance

• Disconnect power to the appliance before starting any repair
• Remove the outer console or control bezel to access the keypad per the OEM service instructions
• Handle the membrane and any ribbon cable carefully to avoid creasing or damaging connectors
• Reconnect and test the control functions before fully reassembling the console

This system PCB assembly is the appliance's main electronic control board that manages key functions and cycles, restoring responsive controls and reliable operation when the original board fails. What it does:

• Receives inputs from the control panel and sensors to operate motors, valves, and other components
• Regulates timing, user-selected cycles, and safety interlocks for proper appliance performance
• Can address symptoms like unresponsive controls, erratic or intermittent operation, or failure to start
• Replaces a failed or damaged main control board to restore normal electronic control

• Disconnect power before service to avoid shock or damage
• Handle the board carefully; avoid static discharge and physical impact
• Confirm connector orientation and seating during reassembly

This power control board is the appliance's main power distribution and control module, restoring proper electrical control so the unit can start and run reliably. It replaces a failed or damaged control board to return normal operation. What it does

• Routes power and control signals to internal components so motors, valves and other systems operate.
• Receives commands from the user interface and provides the control outputs that run cycles and functions — can address unresponsive controls or no-start conditions.
• Regulates and distributes voltage across subsystems to prevent inconsistent or intermittent operation.
• Interfaces with sensors and safety switches to manage cycle behavior and help prevent unsafe operation.

• One power control board.

• Disconnect all power before servicing to avoid shock; verify power is off at the breaker or unplug the appliance.
• Handle the board by its edges and use anti-static precautions to avoid damage to electronic components.
• Note connector orientation and mounting screw locations during removal; transfer any mounting brackets or standoffs to the new board if required.
• Test the appliance after installation and follow the manufacturer's service manual for diagnostic steps.

Power Control Board Assembly manages power distribution and electronic control for the appliance, restoring proper sequencing, user-interface response, and safety interlocks so the unit operates reliably when the original board fails. What it does:

• Regulates power to major components and coordinates operational sequencing for cycles and functions.
• Processes inputs from the control panel and sensors to start, stop, and change modes.
• Common symptoms that indicate board failure: no power or display, unresponsive controls, intermittent operation, or erratic behavior.
• Replaces a damaged or burned control board that causes electrical or control faults.

• Disconnect all power to the appliance before servicing to avoid shock or damage.
• Handle the board by its edges and use static-safe precautions (ESD wrist strap recommended).
• Inspect wiring harnesses and connectors for heat damage or corrosion; ensure secure connections when installing the new board.

A circular lug designed to join a stripped wire to a threaded terminal for a secure electrical connection. Helps restore reliable contact at terminals and reduces the chance of intermittent power or arcing at connection points. What it does:

• Provides a strong mechanical and electrical connection between a wire and a screw or bolt terminal.
• Helps prevent loose connections that can cause intermittent operation, sparking, or overheating.
• Commonly used where a ring-style termination is required for safe, stable wiring.
• Works with properly sized wire and fasteners to maintain consistent conductivity.

• Always disconnect power to the appliance before inspecting or replacing electrical parts.
• Use the correct lug size and gauge for the wire and terminal; crimp or solder per manufacturer recommendations.
• Tighten terminal hardware to the appliance manufacturer's specified torque; avoid over-tightening which can damage the lug or terminal.
• If wiring insulation or the terminal is damaged or corroded, replace the affected components rather than reusing them.
