• 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

This holder secures the door lock assembly to the washer, keeping the latch and lock mechanism aligned for reliable door closure and operation. Replaces a worn or broken lock mounting bracket to restore proper door engagement. What it does:

• Mounts and supports the washer door lock assembly to keep the latch aligned
• Holds the lock in place so the door can fully close and lock during cycles
• Common symptoms: door won't latch, door comes loose, washer won't start, or door/lock error codes
• Prevents excessive movement that can damage the lock or striker

• Unplug the appliance and turn off water supply before beginning work
• Basic hand tools (screwdriver, nut driver) are typically required; keep fasteners for reassembly
• Handle edges and the door/lock assembly carefully to avoid damage

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

The Grille, Vent is an OEM part for LG microwaves. It is a component located on the outside of the microwave that is responsible for ventilating heat and providing airflow. 

Symptoms of a bad grille, or vent can include blockages preventing proper ventilation, deformations or dents that disrupt airflow, or loose or missing mounting brackets. Without proper functioning of this vent grille component, the microwave may overheat during use or function improperly. 

Causes of a bad grille, vent include normal wear and tear over time, accumulated debris buildup causing obstructed ventilation, or physical damage due to impact or mishandling.

Symptoms of a bad vent grille include:

• Overheating or shutting down of the microwave 
• Reduced cooking power
• Accumulation of heat inside the microwave cavity
• Tripped breaker or fuse

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

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.
