Parts for Lg LRE3012SB: Controller 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.

This Barrier is a protective panel designed to shield internal components and help maintain proper airflow and separation inside the appliance. It reduces risk of component damage and keeps internal areas cleaner for reliable operation. What it does

• Protects delicate internal parts from physical contact, debris, and incidental impact
• Helps maintain intended airflow paths to support proper component cooling or ventilation
• Prevents contact between moving parts and wiring or sensors
• Can reduce dust buildup in sensitive areas that could affect performance

• One Barrier protective panel

• Disconnect power and, for appliances with water supply, shut off water before starting work
• Handle the panel carefully to avoid bending or damaging mounting tabs
• Use only OEM-recommended fasteners and placement;

This rear cover is the exterior cabinet panel that protects the appliance's internal components from dust, debris and accidental contact. It restores the appliance's outer protection and helps maintain safe operation. What it does

• Shields motors, wiring and internal components from debris and accidental contact
• Restores the appliance's sealed outer cabinet to help prevent dust and moisture intrusion
• Stops rattles or vibration caused by cracked or missing rear panel mounting
• Improves safety by covering sharp or moving internal parts

• Unplug the appliance or shut off power at the breaker before starting
• Remove any screws or fasteners securing the old rear cover; save hardware
• Support the appliance cabinet while aligning the new panel, then fasten securely
• Handle edges carefully; inspect surrounding seals and mounting clips and replace if damaged

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.

The PCB Assembly is an OEM component for LG ranges. It is the circuit board responsible for controlling critical range functions such as the oven, cooking elements, and display. 

Symptoms of a bad PCB assembly can include: 

• Range elements not working properly 
• Display malfunctions or failures 
• Improper functioning of oven features like bake, broil, and convection modes 

Causes of a bad circuit board tend to be normal wear and tear over time from heavy usage and heat exposure during cooking. Occasional power surges or fluctuations can also potentially cause circuit damage. 

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