Parts for Lg LRE30453ST/00: Controller Parts

This is a truss-head tapping screw used to secure trim, panels, and small assemblies on compatible LG appliances. It provides a low-profile, wide-bearing head that helps hold parts flush and resist pull-through. What it does:

• Fastens plastic and sheet-metal components where a self-tapping thread is needed
• Truss head spreads load to prevent damage to soft or thin materials
• Helps secure control panels, brackets, or trim pieces that require a low-profile head
• Common replacement when original mounting screws are missing, stripped, or corroded

• One truss-head tapping screw

• Use the correct screwdriver bit and moderate torque to avoid stripping the screw or workpiece
• Start threading straight and let the screw form threads without forcing at an angle
• Disconnect power and follow appliance-specific service safety procedures before working internally
• Replace any damaged mating threads or clips for a secure fit

The PCB Assembly is an OEM replacement part for LG ranges. This component serves as the brain of the appliance, hosting and connecting various electronic components. It is instrumental in managing and coordinating the functions of the range, ensuring it operates efficiently and effectively.

Symptoms of a bad PCB Assembly include:

• The oven or burners not heating up or maintaining the set temperature
• The display panel malfunctioning or showing error codes
• The range's features, like timers or sensors, not working correctly
• Unusual noises or behaviors during the operation

Causes for a malfunctioning PCB Assembly can be varied, including electrical surges, wear and tear over time, or issues with the internal components and connections on the board.

This OEM LG part is also compatible with Sears/Kenmore ranges.

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.
