Parts for Lg LDG3015ST/00: Controller Parts

This truss head tapping screw secures interior panels and small components on compatible appliances, restoring proper fit and stopping rattles or loose trim. It's a direct hardware replacement for a single mounting point. What it does:

• Fastens panels, brackets, and trim where a low-profile truss head is required
• Replaces missing or stripped screws that cause rattling or loose parts
• Provides a secure hold by forming threads in sheet metal during installation
• Useful for repairing cosmetic or functional panel alignment issues

• Disconnect power before working on any appliance to avoid shock or injury
• Use the correct sized Phillips or Torx driver to prevent cam-out or screw damage
• Start straight and thread slowly; do not overtighten to avoid stripping sheet metal
• Replace only with the exact part number for best fit and performance

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.

This supporter is a small mounting bracket that holds internal components in place to keep assemblies aligned and reduce vibration. Replacing a damaged supporter restores proper fit and steadies moving parts for quieter operation. What it does:

• Secures internal assemblies or panels to the appliance frame to prevent shifting
• Maintains alignment so doors, drawers or moving parts track correctly
• Dampens vibration and reduces rattling or knocking noises from loose components
• Prevents wear or damage caused by parts moving out of position

• Disconnect power (and water if applicable) before starting any repair.
• Access may require removing exterior panels or covers; keep fasteners organized.
• Install with the correct screws and hand tools; do not over-tighten to avoid cracking the bracket.
• Inspect neighboring clips, screws and supports while replacing this part; replace any additional damaged hardware.

This power transformer assembly converts incoming line voltage to the lower-voltage supply used by the appliance's control electronics. Replacing a failed transformer restores proper power to control boards and related circuits. What it does:

• Converts house voltage to the control circuit voltage used by the appliance
• Supplies stable power to the main control and display electronics
• A faulty transformer can cause power loss to controls, no display, or intermittent operation
• Works as part of the appliance's electrical supply and control system

• Disconnect all power to the appliance before beginning work to avoid shock
• Handle the assembly and its connectors gently; avoid bending pins or wiring
• Verify connector orientation and secure mounting before reapplying power

This factory-specified parts assembly replaces a damaged or missing original assembly in your appliance. Restoring the correct fit and function of the affected components helps the unit operate as designed after wear, damage, or prior service.

• Direct replacement for the assembly identified in your model's parts diagram
• Can help resolve loose or misaligned components, vibration/rattling, or incomplete installation
• Matches original design for consistent fit and performance
• Useful when original pieces are lost or damaged during service

• Disconnect power before service; shut off gas or water if applicable
• Allow the appliance to cool; wear cut-resistant gloves for sharp edges
• Use your model's service manual/parts diagram to take reference photos
• Reassemble panels and test operation after installation

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.
