This lower-front grille, or kickplate, covers the base opening of your appliance to protect internal components and help guide airflow. Replace a damaged or missing grille to restore a clean, finished look and proper fit at the bottom front.

• Mounts at the base as the toe-kick panel
• Shields condenser/under-cabinet components and helps channel airflow
• Restores the appliance's finished appearance
• Replace if cracked, warped, missing, or won't stay attached
• Can reduce rattling caused by a loose or broken grille

• Unplug the appliance before servicing; use gloves to protect hands
• Remove any retaining screws or release clips; pull the old grille straight out
• Align tabs or screw holes and snap/secure the new grille in place
• Ensure the grille is fully seated and does not interfere with door operation

This replacement lamp socket holds the light bulb and provides a stable electrical connection so your appliance light works reliably. Replace a heat-damaged or loose socket to restore consistent illumination and help prevent flicker, arcing, and premature bulb failure.

• Secures the bulb and connects it to power
• Restores proper interior or work-area lighting
• Addresses flickering, intermittent light, or bulbs failing early from poor contact
• Replaces sockets that are cracked, melted, or discolored

• Disconnect power at the breaker or unplug before servicing
• Allow the area to cool; wear gloves and safety glasses
• Note wire positions and transfer one lead at a time to the new socket
• If servicing a microwave, access only the lamp area per your model instructions; do not open the cabinet—internal components can retain high voltage

This humidity sensor assembly monitors moisture inside the microwave cavity during Sensor Cook and Reheat cycles, allowing the control to automatically adjust time and power. Replacing a failed sensor can restore accurate, reliable sensor-based cooking performance. What it does:

• Detects steam/humidity in the cavity for auto-sensing cook and reheat programs
• Sends feedback to the control board to adjust power levels and cook time
• Failure symptoms include sensor cook not starting, stopping early, "sensor" error messages, or inconsistent results on auto settings

• One humidity sensor assembly

• Unplug the appliance before service; microwaves contain a high-voltage capacitor that can retain a dangerous charge
• Handle the sensor face carefully and keep it clean; route and secure the wire harness as originally

This turntable coupler connects the microwave's turntable motor to the glass tray, rotating it for even, consistent heating. Replace a worn or cracked hub to restore smooth tray motion and reduce noise during cooking.

• Couples the turntable motor to the glass tray for even heating
• Replaces a worn, cracked, or stripped hub that prevents rotation
• Helps reduce tray wobble and scraping sounds from the center
• Common symptoms: tray not turning, intermittent rotation, clicking/grinding at the hub

• Disconnect power before servicing; microwaves contain high-voltage components
• Remove the glass tray and roller ring; lift the old coupler straight up from the motor shaft (some models may require access from below per instructions)
• Align the new coupler with the keyed motor shaft and press it fully into place
• Reinstall the roller ring and tray; verify smooth, centered rotation

Stirrer fan cover that protects and secures the microwave's stirrer fan assembly, helping keep food debris out and the rotating stirrer operating smoothly to reduce noise and maintain consistent performance. What it does:

• Encloses and shields the stirrer fan assembly from food particles and foreign objects.
• Keeps the stirrer properly positioned so the fan and stirring mechanism can rotate without interference.
• Helps limit vibration and rattling caused by a loose or damaged cover.
• Visible cracks or breaks in the cover can lead to noisy operation, poor stirring action, or intermittent fan contact.

• Disconnect power before servicing the appliance to avoid shock or injury.
• Replacement requires removal of the microwave outer cabinet and access to the stirrer/fan area; retain all mounting screws and hardware.
• Inspect surrounding parts when replacing the cover; do not operate the appliance with a cracked or missing cover.
• Use the correct part number to ensure fit and function.

This door interlock micro switch is part of the microwave's latch assembly. It detects when the door is fully closed so the oven only runs when latched, helping restore safe, consistent start/stop operation.

• Senses door-latch position within the interlock assembly
• Cuts power when the door opens; permits operation when fully closed
• Helps resolve "won't start" complaints or stopping when the door is jostled
• Often fixes the need to press or lift the door to keep the unit running

• Unplug the microwave before servicing; high-voltage components can retain a dangerous charge.
• Access the interlock/latch bracket behind the control panel; note switch orientation and terminal labels (COM, NO/NC).
• Transfer wires to the new switch, secure it in the bracket, and ensure the actuator aligns with the door latch.
• Reassemble and test with a cup of water to ensure proper start/stop operation.

This customized nut is a small fastener used to secure components inside an appliance. Replacing a stripped, rusted, or missing nut restores a tight hold, reduces vibration, and helps keep panels and brackets properly aligned.

• Match the thread size/pitch to the original fastener before installation
• Hand-start threads to avoid cross-threading; tighten until snug—do not overtighten
• Replace any worn companion hardware (screw/bolt/washer) as needed

This thermostat is a temperature-sensitive safety switch for select LG microwaves. It monitors heat at its mounting point and interrupts power when overheating is detected, helping protect internal components and restore operation once temperatures return to normal.

• Monitors temperature at its mounting location inside the microwave
• Opens the circuit to interrupt power when temperatures exceed its rating
• Helps prevent heat-related damage to internal components
• Failure symptoms include mid-cycle shutoff, no heat or no start after an overheat event, or abnormal vent/cooling fan operation

• Disconnect power at the outlet or breaker before servicing
• Microwaves contain a high-voltage capacitor; discharge it properly before touching internal parts
• Note wire positions and transfer one lead at a time; mount the thermostat firmly for accurate heat sensing
• Inspect and replace any burnt connectors; ensure clean contact with the mounting surface

This door latch assembly for a microwave engages the door hooks and actuates the interlock switches so the unit recognizes a closed door, restoring proper latching and helping ensure the oven only operates when securely shut.

• Discharge the high-voltage capacitor before servicing
• Note wire positions and transfer one lead at a time; ensure tight connections
• Mount firmly and flush to the original location/bracket for proper thermal contact

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.
