A small replacement fastening nut used to secure components on LG appliances. Replacing a worn or missing nut restores a secure fit and helps eliminate looseness or rattling for reliable operation. What it does

• Fastens and secures mating parts or hardware on appliance assemblies
• Stops movement that can cause rattling, vibration, or misalignment
• Useful when a nut is stripped, lost during service, or damaged
• Helps maintain safe, stable operation of the repaired area

What's included One nut as shown Install notes

• Disconnect power and water before servicing the appliance
• Verify the nut matches the original by thread, size, and profile before installation
• Hand-thread first to avoid cross-threading, then tighten with the correct tool; avoid overtightening
• Keep small parts away from children and pets during repair

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

Thermistor is a temperature-sensing replacement that monitors refrigerator and freezer temperatures so the control board can regulate cooling. Replacing a faulty thermistor restores accurate temperature readings and helps stabilize cooling performance. What it does:

• Senses interior/evaporator temperature and sends a signal to the control board for temperature regulation.
• Helps prevent erratic cooling, long run-times, or inconsistent compartment temperatures when operating correctly.
• Faulty thermistors can contribute to excessive frost, failed defrost cycles, or compressor cycling issues.
• Use when the existing sensor fails to report correct temperatures or the part number matches.

• Always disconnect power to the appliance before servicing to avoid shock or damage.
• The sensor is typically mounted on or near the evaporator or inside a cabinet wall; access may require removing panels or covers.
• Handle the sensor and wiring harness gently; avoid pulling on wires or bending the sensor element.

A replacement glass shelf that provides a sturdy, easy-to-clean surface for storing food inside your refrigerator. Restores lost or damaged shelving to help keep items organized and stable. What it does:

• Replaces a cracked, chipped or missing interior glass shelf so food no longer sits unevenly or risks falling.
• Provides a solid, flat surface for bins, containers and loose items.
• Helps maintain proper airflow by fitting into the intended shelf supports.
• Matches original OEM fit and finish for a flush, secure installation.

• Remove all items from the surrounding area and support adjacent shelves before installing.
• Slide into existing shelf tracks until it rests securely on the supports; do not force.
• Handle with care to avoid chipping; wear gloves to reduce cut risk.
• If glass is broken, remove debris carefully and unplug the appliance before cleaning the area.

This is a replacement screw used to secure appliance components and panels. It restores proper fastening where a stripped, missing, or damaged screw causes loose parts or rattling. What it does:

• Fastens panels, trim, or internal components to maintain structural fit
• Helps stop vibration-related noise from loose assemblies
• Replaces missing or corroded screws that prevent proper closures
• Restores secure mounting after repairs or disassembly

• Use the correct screwdriver or bit to avoid stripping the head
• Tighten until snug—do not over-torque to prevent thread damage
• Keep small parts away from children and pets
• Disconnect power or water before accessing internal parts

This 4.0x16mm tapping screw secures trim and internal components on compatible appliances, providing a reliable fastener for repair or reassembly. Use the correct screw to maintain fit and function during service. What it does:

• Fastens appliance panels, brackets, and small components where a self-tapping thread is required
• Replaces stripped or missing screws that cause loose panels or rattling
• Helps restore proper alignment and secure electrical or mechanical parts
• Suitable where a 4.0 x 16mm size and tapping/sharp thread are specified

• One 4.0x16mm tapping screw (quantity: 1)

• Use the matching screw location and thread engagement; do not force a misaligned fastener
• Tighten until seated; avoid over-torquing which can strip threads or crack plastic
• Disconnect power and follow appliance safety procedures before servicing
• If screws repeatedly strip, inspect mating threads or use an approved repair insert

This replacement door handle restores a secure, easy-grip opening for your appliance door and refreshes the exterior appearance. Designed to match the original fit and function for a clean, factory-style repair. What it does:

• Provides a firm grip to open and close the appliance door smoothly
• Replaces cracked, broken, loose, or missing handles that impede door use
• Restores proper alignment and helps prevent accidental slippage when opening
• Improves the appliance's appearance by replacing a worn or damaged handle

• Disconnect power to the appliance (or unplug) before starting work; if applicable, turn off water supply for connected appliances.
• Most installations require removing a few screws or clips—have a Phillips screwdriver and trim tool handy.
• Retain original fasteners if they are undamaged; replace any stripped screws.

This is the glass turntable tray for a microwave. It supports your dishes and rotates with the drive system to help food heat evenly. Replace a cracked, missing, or slipping tray to restore steady, reliable turntable rotation.

• Provides a flat, stable surface for cookware during cooking and reheating
• Sits on the roller guide and engages the center drive coupler to rotate food
• Promotes more even heating by turning food through the microwave energy field
• Typical failure signs: cracked/chipped glass, wobbling, slipping, or the tray not turning correctly

• Disconnect power before servicing and handle glass carefully
• Remove the old tray; wipe debris from the roller ring and cavity floor
• Align the tray's center hub with the drive coupler and set it on the roller ring; ensure it sits flat and spins freely
• Test rotation with a microwave-safe cup of water

A high-voltage capacitor for the appliance's high-voltage circuit that stores and releases electrical energy to support proper heating operation. Replacing a failing capacitor can restore consistent heating and prevent related electrical faults. What it does:

• Stores and delivers high-voltage energy used by the magnetron/ high-voltage assembly to generate heat.
• Failure may cause no-heat or weak-heat conditions in the oven.
• Faulty capacitors can contribute to arcing, loud humming, or blown high-voltage fuses.
• Works as part of the HV circuit; not a user-serviceable low-voltage control.

• High-voltage components can hold a dangerous charge—disconnect power and discharge the capacitor before servicing.
• Use insulated tools and avoid touching terminals; verify proper operation with appropriate test equipment.
