Parts for Lg LDG3037ST/00: Controller Parts

This replacement power control board is the main PCB that manages and distributes electrical power to the appliance's components, restoring proper power-related functions and control when the original board fails. What it does:

• Regulates and supplies voltage to motors, sensors, and user interface circuits
• Controls startup and shutdown sequences for safe operation
• Helps stop symptoms like no power, intermittent power loss, or erratic component behavior
• Works with other control boards and sensors to maintain normal appliance operation

• Disconnect power (unplug or trip breaker) before servicing to avoid shock
• Wear an anti-static wrist strap or discharge static before touching the board
• Verify connector locations and cable seating match the original before reassembly

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.
