Parts for Lg LRG3091ST/00: Controller Parts

This is the main PCB power control board assembly that manages power distribution and control signals for the appliance, restoring proper electrical and control functions when the board has failed. What it does:

• Controls power delivery and coordinates electronic functions across the appliance
• Replaces a failed control board that causes unresponsive buttons or no power to the unit
• Can resolve intermittent operation, unexpected shutdowns, or incorrect cycle behavior linked to control electronics
• Address blank or erratic display and certain control-related error codes

• Disconnect power (unplug or flip the breaker) before starting work.
• Handle the PCB by the edges and avoid static discharge — use an anti-static wrist strap if available.
• Verify connectors match and seat fully; do not force connectors or bend pins.

The PCB Assy Power is an OEM part for LG gas ranges. It regulates and monitors the electrical control systems to safely operate burners, oven functions, and auxiliary components. The power board receives inputs from the control panel and thermocouples to distribute outputs that power components including ignitors, valves, and fans. 

Causes of a bad power board can include liquid damage, failures due to intense heat cycling over time, and issues arising from manufacturing defects.

Symptoms of a bad PCB Assy Power include:

• Burners not igniting or functioning properly
• Oven not heating or baking as expected 
• Faulty or unresponsive control panel 
• Error codes displayed

This genuine LG replacement ensures the range's control and safety systems perform reliably. It is also suitable for ranges by Sears/Kenmore containing LG mechanisms and electrical hardware. Installing this high-quality OEM board protects your investment and restores full functionality.

This supporter is a small mounting bracket that holds internal components in place to keep assemblies aligned and reduce vibration. Replacing a damaged supporter restores proper fit and steadies moving parts for quieter operation. What it does:

• Secures internal assemblies or panels to the appliance frame to prevent shifting
• Maintains alignment so doors, drawers or moving parts track correctly
• Dampens vibration and reduces rattling or knocking noises from loose components
• Prevents wear or damage caused by parts moving out of position

• Disconnect power (and water if applicable) before starting any repair.
• Access may require removing exterior panels or covers; keep fasteners organized.
• Install with the correct screws and hand tools; do not over-tighten to avoid cracking the bracket.
• Inspect neighboring clips, screws and supports while replacing this part; replace any additional damaged hardware.

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.
