The Diode Assembly is an OEM replacement part for LG microwaves. As an electrical part, it plays a key role in regulating power distribution throughout the microwave. 

Symptoms of a bad diode assembly can include:

• Lights or displays failing to illuminate  
• Inability to power the microwave or select cooking functions
• Intermittent or unexpected shutting off during use
• Sparking, burning smells or tripped circuit breakers

Causes may arise from repetitively fluctuating power loads degrading individual diodes over time. Moisture intrusion into electrical pathways can also cause issues.

This genuine LG OEM assembly is also compatible with some Kenmore microwave models as well. 

The Door Lock holder assembly is an OEM replacement part for LG microwaves. It is a component responsible for securely holding the microwave door in place and locking it closed. The door holder assembly works with other components like the door hinges and latch mechanism to provide a tight seal when cooking or warming food items.

Causes of a bad holder assembly can include wear and tear from frequent use, physical damage from slamming the door, or misalignment affecting its ability to lock the door.

Symptoms of a bad holder assembly include:

• The microwave door not staying closed
• The microwave not starting or operating due to door issues
• The door feeling loose or wobbly
• Audible clicks or resistance when attempting to close the door

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

The Locker is an OEM replacement part for LG microwaves. It is a metal hook located on the side of the microwave door that securely fastens the gasket and seals when closed. The door hook ensures a tight compressive fit of the door gasket all around the perimeter of the door opening. 

Symptoms of a bad door hook include:

• Gaps appearing around the door seal allowing steam or heat to escape  
• The door not sitting flush and securely closed
• Risk of accidental opening during a cooking cycle
• Reduced heating efficiency 

Causes tend to be normal wear over time, like dulling or bending of the thin metal hook. Impact or over-tightening could potentially damage or deform the hook.

This part is also compatible with Sears/Kenmore microwaves.

The Choke Cover is an OEM part for LG microwaves. This is a protective shield that covers the microwave’s internal components, preventing interference and ensuring the safe operation of the microwave.  

Causes of a bad choke cover can include physical damage from accidental impacts, deterioration due to prolonged use, or exposure to high temperatures.

Symptoms of a bad choke cover include:

• Unusual noises during microwave operation
• Visible cracks or damage to the cover
• Microwave not heating food properly
• Sparks or arcing inside the microwave

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

The Diode is an OEM replacement part for LG countertop microwave models. Located internally on circuit boards regulating magnetron function, it precisely controls the electric current flow.

Causes of a bad diode involve thermal fatigue over time putting repetitive stress on sensitive semiconductor junctions. Microwave demands may accelerate failures.

Symptoms include:

• Intermittent cooking or complete failure to energize the tube
• Error codes appearing on the control panel display
• Buzzing or humming noises emitting from internal circuitry

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

This microwave turntable assembly supports and rotates the glass tray so food heats more evenly. Replacing a damaged turntable restores smooth, stable rotation and reliable heating performance.

• Supports dishes on the glass tray and rotates them during cooking
• Engages the drive coupler to help promote more uniform heating
• Replaces a cracked, chipped, or missing turntable assembly
• Can help address wobbling, scraping noises, or failure to turn when the tray/support are damaged

• Disconnect power to the microwave before servicing
• Remove the old tray; clean the turntable track of debris
• If your model uses a roller ring, place it on the track, then seat the tray on the center coupler; ensure it sits flat and spins freely
• Do not operate the microwave without the turntable properly installed; inspect the drive coupler and turntable motor

The Halogen Lamp is an OEM part for LG microwaves. It illuminates the interior of the microwave, allowing you to monitor the cooking process without opening the door.

Common causes of a bad halogen lamp include prolonged usage, electrical surges, or damage from impacts.

Symptoms of a bad halogen lamp include:

• The microwave interior remaining dark during operation
• Flickering or dim lighting
• The lamp not turning on at all

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

This holder assembly secures the locker/latch mechanism in place so the door or access panel aligns and closes properly. Replacing a cracked or missing holder restores secure engagement and smooth, reliable operation. What it does:

• Supports and positions the locker/latch mechanism
• Maintains alignment for consistent latching and closing
• Common symptoms of a failed holder: loose latch feel, misalignment, door/panel not staying closed, or visible cracks/broken mounts
• Direct-fit replacement to restore proper support

• 1 holder assembly

• Disconnect power to the appliance before servicing.
• Access the locker area and retain any screws/clips; transfer any reusable hardware from the original holder as needed.
• Align the new holder with existing mounting points and tighten screws evenly—do not overtighten.
• Test latch engagement and door/panel operation before final reassembly.

The Halogen Lamp is an OEM part for LG microwaves. This lamp is designed to provide illumination underneath or inside the select microwaves, allowing for better visibility inside the cavity or the cooking space below the microwave. 

Causes of a bad part can include the lamp reaching the end of its lifespan due to normal use, electrical issues causing premature burnout, or physical damage from impact or exposure to heat.

Symptoms of a bad Halogen Lamp include:

• Dimming or flickering of the lighting
• Complete failure of the light to turn on
• Visible damage or burn marks on the lamp itself

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

This mounting plate is a metal bracket used to secure the microwave chassis/components in the correct position. A worn or damaged plate can cause poor fitment, vibration, or noise during operation.

• Provides a stable mounting surface for the designated microwave assembly
• Helps reduce vibration and rattling noises
• Restores proper alignment if the original plate is bent or broken
• Commonly replaced when the original plate is damaged or missing

• Unplug the appliance and discharge the high-voltage capacitor before servicing a microwave
• Use proper personal protective equipment; metal edges can be sharp
• Note orientation and fastener locations before removal
• Tighten mounting hardware evenly to avoid distortion

The Thermostat is an OEM part for LG microwaves. This part monitors and regulates the temperature within the appliance. The thermostat ensures that the microwave does not overheat, automatically shutting off the power if the internal temperature exceeds safe levels. This preventive measure helps to avoid damage to the microwave and potential safety hazards in the kitchen. 

Causes of a bad thermostat can range from normal wear and tear, which may cause the component to lose its calibration over time, to overheating incidents that permanently damage its sensitivity.

Symptoms of a bad Microwave Thermostat include:

• The microwave unexpectedly turning off during use
• The microwave failing to start
• Inconsistent cooking temperatures or unevenly cooked food

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