Parts for Lg LDE3037SB: Controller Parts

Direct-replacement main PCB that manages the appliance's electronic controls and power functions to restore reliable operation when the original control board fails. Helps address control faults and intermittent power-related behavior on compatible units. What it does:

• Regulates power and electronic communication between sensors, switches and actuators.
• Runs control logic for cycles, timers and user commands.
• Can correct symptoms such as unresponsive controls, intermittent power, erratic cycles or persistent control-board error codes.
• Replaces a failed or damaged main control board to restore normal electronic operation.

• Disconnect power to the appliance before beginning any work; verify power is off at the breaker.
• Use ESD precautions (ground strap or touch a grounded metal surface) to avoid damaging the PCB.
• Verify this exact PCB is the correct replacement for your model before installation.

This display power control board assembly powers and controls the appliance's front display and user interface so the screen lights up and responds to touch or button commands. Replaces a failed display/control module to restore visible controls. What it does:

• Supplies power to the front display and backlight so icons and numbers are visible
• Processes user inputs from the touchpad/buttons and forwards signals to the main control
• Helps display error codes and status information for diagnostics
• Commonly replaced for a blank, dim, flickering, or unresponsive display

• One display power control board assembly

• Disconnect power to the appliance before starting to avoid shock or damage
• Handle the board by its edges and avoid static discharge; use an anti-static wrist strap if available
• Some disassembly of the control panel or console is usually required; keep screws and fasteners organized
• After installation, verify function by restoring power and testing all display functions and buttons

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.

This single wire harness connects controls and components to deliver power and signals so affected functions run correctly. It replaces a damaged harness to restore reliable electrical connections and consistent operation. What it does:

• Transfers power and control signals between the control board and individual components
• Restores missing or intermittent power to components when a harness is damaged
• Prevents shorts and poor connections caused by frayed wires or broken terminals
• Typical symptom: appliance or specific functions do not power up, run intermittently, or behave erratically

• Disconnect power to the appliance before starting any work.
• Match connector shapes and wire colors; seat each connector fully until it clicks.
• Route the harness following existing clips and retainers to avoid chafing or pinching.
• If terminals are corroded or connectors are damaged, replace the harness rather than attempting repairs.

This single wiring harness connects electrical components to restore reliable power and signal routing within the appliance. It replaces damaged or burnt harnesses to help return normal operation and prevent intermittent faults. What it does

• Routes power and signal between control boards, sensors, and motors for proper operation
• Replaces frayed or melted wiring that can cause intermittent function or component failures
• Helps resolve symptoms like no power to a component, intermittent operation, or error codes related to open circuits
• Restores factory wiring organization and secure connector fit for reliable connections

• One wiring harness assembly

• Disconnect power before servicing to avoid shock or damage
• Verify connector orientation and fully seat all plugs; do not force connectors
• Replace only with the exact harness to maintain correct wire lengths and connector types

This single wire harness connects electrical circuits inside the appliance to restore reliable power and signal routing. It replaces a damaged or worn harness to help components receive proper power and reduce intermittent failures. What it does:

• Reestablishes electrical connection between internal components and control circuits
• Restores power/signal routing when factory wiring is damaged, frayed, or burnt
• Helps stop intermittent operation, no-power conditions, or component failures caused by wiring faults
• Matches OEM wiring colors and connector types for a direct replacement

• Disconnect power before servicing to avoid shock or injury.
• Compare harness shape, connector count, and pin orientation to the original before installation.
• Route harness away from sharp edges and heat sources; secure with existing clips or ties.
• If connectors are damaged or pins bent, replace the harness—do not attempt temporary fixes.

This parts assembly is a factory replacement assembly that restores the appliance's original fit and function. Use it to replace a damaged, worn, or missing assembly for reliable component alignment and operation. What it does:

• Replaces a damaged or broken assembly to restore proper mechanical fit
• Restores secure mounting and alignment of connected parts
• Helps eliminate rattles, looseness, or intermittent operation caused by a failed assembly
• Matches OEM form and connection points for a direct replacement

• Disconnect power and water before starting any repair
• Handle connectors and wiring gently; do not force connections
• Use basic hand tools; verify correct orientation before tightening fasteners

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.
