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.

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.

• Disconnect power to the appliance before starting any repair to avoid electrical or injury risk
• Typically installs with the original mounting screws or clips; keep existing fasteners and align the handle before tightening
• Use basic hand tools (screwdriver) and avoid overtightening to prevent stripping or cracking
• If trim or door panels must be removed, keep small parts organized and follow manufacturer instructions

This is a motor start/run capacitor that helps the appliance's motor start and run smoothly by supplying a brief boost of electrical energy. Replacing a failing capacitor restores reliable motor startup and operation. What it does:

• Provides the brief electrical surge needed to start and keep the motor running
• Commonly linked to motors that hum, fail to start, or run intermittently
• Helps prevent overheating from repeated start attempts when functioning properly
• Works with the appliance's start circuitry to ensure consistent performance

• Disconnect power to the appliance before accessing electrical components
• Discharge the capacitor and use insulated tools
• Observe polarity/terminal layout and secure connections to factory specifications
• Dispose of the old capacitor according to local electronic-waste regulations

A Tap-Tite binding-head screw used to fasten appliance panels and components where a self-tapping metal thread is required. Replaces missing or damaged fasteners to restore secure assembly and reduce vibration or rattling. What it does:

• Creates its own mating thread in thin sheet metal for a secure hold without a nut.
• Holds panels, brackets, and trim in place to prevent looseness or movement.
• Commonly used where stripped, missing, or broken screws cause rattling, misalignment, or parts that won't stay attached.
• Compatible with standard screwdrivers or nut drivers sized to the binding-head.

• Disconnect power and unplug the appliance before working on it.
• Use the correct driver bit to avoid cam-out or head damage.
• Start straight and apply steady pressure; avoid overtightening to prevent stripping the formed threads.
• If the original hole is badly damaged, assess for repair or use of a larger fastener as needed.

This factory fastener secures appliance panels and components. Use it to replace a missing, stripped, or corroded screw so brackets, covers, and assemblies stay tight and properly aligned, helping reduce vibration and rattling.

• Secures panels, brackets, and internal components in their proper positions
• Replaces missing, worn, or cross-threaded hardware
• Helps eliminate vibration and rattling from loose parts
• Supports proper alignment of covers and assemblies

• Disconnect power to the appliance before servicing; allow any moving parts to stop
• Match this screw to the location shown in your model's parts diagram
• Start threads by hand to avoid cross-threading, then tighten snugly with the correct driver
• Do not overtighten to prevent stripping threads or cracking plastic bosses

Size: 5 inches x 7 3/4 inches.

This outer door window glass replaces a cracked or cloudy viewing panel so you can safely monitor cooking without opening the door. Tempered glass matches OEM fit and restores a clear view through the appliance door. What it does:

• Provides a clear, protective viewing panel for the appliance door
• Restores safe visibility when original glass is cracked, chipped, or fogged
• Helps contain heat and splatter behind the door during operation
• Matches OEM shape for correct fit and secure mounting

• Handle with care; tempered glass can shatter if dropped or struck
• Disconnect power to the appliance before removing the door or any fasteners
• Follow OEM diagram for door disassembly and reassembly to avoid damage

This temperature control thermostat senses and regulates refrigerator temperature to keep food cold and appliances running efficiently. It replaces a worn or faulty controller to restore proper cooling cycles and temperature stability. What it does:

• Senses cabinet temperature and tells the compressor/evaporator fan when to run
• Restores normal cooling if a failed thermostat causes warm temperatures
• Stops continuous running or short-cycling when the thermostat was the issue
• Helps prevent food spoilage by maintaining consistent temperatures

• Disconnect power before servicing to avoid shock or injury
• Handle terminals and sensing elements carefully; avoid kinking or damaging capillary tubing

The Common Nut is an OEM part for LG ranges. It secures the fan blade to the motor shaft. This nut maintains the fan's stability and preventing it from becoming dislodged during use.

Causes of a bad common nut can include loosening over time due to vibration, improper installation, or damage from impact or mishandling.

Symptoms of a bad common nut include:

• Excessive noise or vibration from the fan assembly
• The fan blade becoming loose or detached, causing poor air circulation
• Potential risk of the fan blade becoming a projectile if completely detached

This OEM LG part is also compatible with some Kenmore models.a
