Parts for Lg LRE30757ST / FSTLLGA: Section 2 Parts

This power control board assembly manages secondary power distribution for the refrigerator's control systems, restoring reliable operation to displays, sensors, and other subcomponents when a faulty board causes power-related failures. What it does:

• Supplies and routes power to subcomponents like displays, user interfaces, sensors, fans, and ice-maker controls.
• Regulates switching between circuits so electronic modules receive the correct voltage when commanded by the main control.
• Faulty units can produce symptoms such as blank or unresponsive displays, intermittent operation, error codes, or a unit that won't power on.

• Disconnect power to the appliance before beginning any repair.
• Handle the circuit board by its edges and avoid touching connectors; follow ESD (electrostatic discharge) precautions.
• Verify the new board matches the original for connector type and mounting points before installing.

This power control board assembly replaces the sub power PCB that manages voltage and signal distribution to the appliance's main controls. Restores control reliability and resolves power-related control issues when the board is at fault. What it does:

• Routes power and control signals between the main control and subsystem components
• Helps the appliance respond correctly to control inputs and cycles
• Commonly replaces a board that causes no power to portions of the appliance or erratic electronic behavior
• Addresses symptoms such as control panel unresponsiveness, intermittent operation, or error codes tied to power/control faults

• Disconnect power before attempting any repair to avoid shock or damage
• Handle the PCB by its edges and avoid static discharge; use proper ESD precautions
• Installation requires basic hand tools and involves removing panels and connectors; keep track of fasteners and wiring
• Replace only with the exact part number to ensure proper fit and function

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.
