Lrg3091st/03 Parts

The Insulator is an OEM part for LG gas ranges. It is a heat-resistant component that helps isolate and insulate internal gas range components from excessive heat. The insulator plays an important role in heat dissipation and preventing overheating of adjoining parts during cooking cycles. 

Causes of a bad insulator include deterioration of the insulation material due to exposure to high temperatures over time from the gas burners. This can cause warping or cracking of the insulator.

Symptoms of a bad insulator include:

• Reduction in heat retention leading to uneven cooking temperatures  
• Conducting excessive heat to non-heating areas of the oven causing unintended warming of components
• Potential gas or fire hazard if insulation breaks down completely

Replace your insulator if you notice any issues to ensure safe operation. This OEM LG replacement insulator restores insulation performance. It is also compatible with Sears/Kenmore gas range models.

This burner tube directs gas from the valve to the oven's burner assembly for proper flame distribution and heat during baking and broiling. Replacing a damaged tube restores safe, even combustion and consistent cooking performance. What it does

• Channels gas to the oven burner so the flame lights and stays steady
• Helps maintain even heat for reliable cooking and browning
• Prevents gas leaks caused by cracks, holes or severe corrosion
• Can resolve symptoms like weak or uneven flames, flame blowouts, or visible tube damage

• Turn off gas supply and electrical power before beginning any service.
• Inspect mounting hardware, gaskets and alignment; replace any worn seals to ensure a proper fit.
• Do not force, bend, or dent the tube during installation; handle carefully to avoid leaks.

This replacement base restores a solid mounting platform for the assembly it supports, keeping components aligned and secure. Replace a cracked or warped base to eliminate looseness, rattling, or misalignment that can lead to premature wear.

• Supports and secures the associated assembly for proper operation
• Maintains alignment to reduce vibration and noise during use
• Helps protect connected parts by preventing shifting and flexing
• Replace when you see cracks, warping, stripped/broken mounts, or symptoms like rattling, looseness, or poor fit

• Disconnect power; shut off water or gas if applicable
• Wear cut-resistant gloves and handle edges carefully
• Document screw locations/routing; transfer any reusable clips or bushings from the old base
• Start screws by hand and avoid overtightening, especially into plastic bosses

This idler bracket mounts the idler pulley or roller in your appliance's tensioning system, keeping a belt or cable aligned and properly tensioned for consistent operation. A bent or worn bracket can cause noise, slippage, or loss of motion.

• Secures the idler pulley/roller in the correct position
• Maintains proper belt/cable tension and alignment
• Helps reduce squealing or squeaking from friction/misalignment
• Can address belts/cables coming off or intermittent movement in the drive mechanism

• Disconnect power; also shut off gas or water before servicing
• Access the tensioner area and note the belt/cable routing and spring orientation
• Relieve tension, remove the old bracket, and transfer the pulley/roller and any spring or hardware as required
• Reinstall the bracket, ensure smooth free movement, route belt/cable correctly, and test operation

The Screw is an OEM component specifically designed for LG ranges. It plays an important mounting and fastening role by securely attaching internal components together.

The screws utilized within the range cabinet ensure sturdy construction and reliable mechanical cohesion. They allow for simple assembly and proper alignment of inner parts. 

Causes of bad screws can include wear and tear over time, or damage from overtightening leading to stripped threads or heads.

Symptoms of bad screws include:

• Loose, detached, or misaligned inner parts  
• Hardware that does not fit or interface as designed
• Unintended noises or movement during the operation

This OEM LG replacement part is also compatible with Sears/Kenmore and some GE ranges utilizing similar fasteners. Replacement ensures the range remains mechanically sound.
 

This cover assembly replaces a damaged or worn poise cover to protect internal components and restore proper fit and appearance. It's a direct-fit replacement designed to keep the area clear of debris and prevent rubbing or misalignment. What it does:

• Protects the poise/internal mechanism from dust, lint, and physical damage
• Restores a secure fit and proper clearance where a cracked or warped cover causes rubbing or noise
• Helps eliminate visible damage that can catch on clothing or interfere with operation
• Useful when the original cover is cracked, broken, loose, or missing

• Disconnect power to the appliance before beginning any repair
• Handle the cover carefully to avoid further cracking; use appropriate fasteners removed from the old part
• Some disassembly of adjacent panels may be required; keep track of screws and small parts

This burner is the cooktop surface flame assembly that produces heat for cooking. It replaces a damaged or worn surface burner to restore proper flame and even heating on the cooktop. What it does

• Provides the primary flame source for a gas cooktop burner
• Restores consistent flame distribution when the original burner is warped, cracked, or clogged
• Can resolve symptoms such as weak or uneven flame, burner that won't sustain a flame, or visible damage to the burner head
• Works with the igniter/safety valve assembly to light and maintain the burner

• One surface burner

• Turn off gas supply and power to the appliance before servicing
• Use basic hand tools; handle the burner carefully to avoid bending or damaging the ports
• Clean burner ports of debris before installation to ensure proper flame pattern
