Parts for Lg LRE3021ST/00: Controller Parts

This display power control board assembly operates the appliance's front display and user interface, restoring display lighting and reliable response so controls show status and accept user commands. What it does:

• Controls display segments, LEDs and backlight; may fix blank, dim, flickering, or garbled displays.
• Processes input from the control panel; can resolve unresponsive or intermittent buttons and touch controls.
• Sends and receives status information with the main control to display cycle information and error indicators.
• Replaces a failed display/control PCB to restore normal interface functions.

• Disconnect power (and water supply if applicable) before servicing to avoid shock and damage.
• Handle the PCB by its edges and use ESD precautions to protect sensitive components.
• Removal typically requires accessing the console or control panel and small hand tools.

The Display PCB Assembly is an OEM part for LG ranges. This part controls and displays the digital interface of the range, providing users with important information such as temperature settings, cooking modes, and timers.

Causes of a bad display PCB assembly can include electrical surges, moisture damage, or general wear and tear over time. 

Symptoms of a bad display PCB assembly include:

• The display not lighting up or being dim
• Inaccurate or scrambled information shown on the screen
• Unresponsive touchpad or buttons
• Error codes appearing without an apparent cause

This OEM LG part is also compatible with some Kenmore models.

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

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.
