Parts for Lg LRE30451SW / AWHELGA: Section 2 Parts

Power transformer that supplies low-voltage power to the appliance control board and user interface, helping restore stable voltage to control circuits for reliable operation of displays and control functions. What it does:

• Steps down incoming mains voltage to the low-voltage level required by the control board and display.
• Replaces a failed transformer that can cause blank or dim displays and unresponsive controls.
• Can address intermittent resets, failure to start, or control-board power-loss symptoms when diagnosed as the faulty component.
• Works with the main control assembly to maintain stable voltage for sensors and interface electronics.

• Disconnect power at the breaker or unplug the appliance before starting any work.
• Handle the control board and connectors carefully; document or photograph wiring locations before removal.
• Reconnect all terminals securely; verify correct orientation and insulation to avoid shorts.

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.
