Parts for Lg LRG3093SB: Controller Parts

A direct-replacement main electronic control board that manages the appliance's user interface, cycles and safety features for normal operation. Restores control functions when the original board has failed. What it does:

• Receives inputs from buttons/sensors and drives the appliance's motors, valves and relays
• Controls cycle timing, displays and status updates
• Common symptom fix: unresponsive controls, no display or intermittent operation
• Common symptom fix: appliance won't start, stops mid-cycle or shows electronic error codes

• One main PCB assembly

• Disconnect power before starting any repair to avoid shock or damage
• Handle the PCB by its edges and avoid touching components; use anti-static precautions
• Verify connectors are seated and wiring matches the service manual diagram
• Some models may require configuration or module pairing per the manufacturer's service instructions

This PCB assembly replaces the appliance's main electronic control board to restore reliable control of functions and user interface. It handles the unit's logic and electrical signals so the appliance can operate correctly. What it does:

• Manages electronic controls and timing signals for the appliance
• Enables display, keypad, and user-interface communication
• Controls outputs for motors, valves, relays and other powered circuits
• Helps resolve intermittent operation, unresponsive controls, or error-code behavior
• Restores proper function when faulty electronics prevent normal operation

• Disconnect power before starting — risk of shock or damage
• Handle the board by the edges and avoid static discharge (use gloves or a grounding strap)
• Keep track of mounting screws and connector orientation for reassembly

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.
