Kenmore Microwave 721.80803400 (72180803400, 721 80803400) Parts

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

This door frame assembly replaces a damaged or cracked outer door frame to restore the washer/dryer door's appearance and structural support. It helps secure the door glass and maintain proper door alignment for safe operation. What it does:

• Replaces a broken, cracked, or warped outer door frame to restore form and function
• Supports and secures the door glass/window to prevent rattling or movement
• Helps maintain correct door alignment so the latch and seal engage properly
• Can reduce drafts, leaks, and vibration caused by a damaged frame

• Disconnect power (and water if applicable) before starting any repair
• Handle glass and frame edges carefully; wear gloves and eye protection
• Retain original screws and mounting hardware unless replacement parts are supplied
• Check door seal/gasket and latch engagement when reinstalling to ensure a proper fit

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 fan assembly replaces a worn or failed fan to restore proper airflow and cooling performance. It installs in the appliance to move air across components for efficient operation and temperature control. What it does:

• Contains the fan motor and blade to circulate air through the appliance
• Restores airflow when existing fan is noisy, slow, or not spinning
• Helps reduce overheating by directing air over coils or components
• Stops symptoms such as unusual fan noise, warm compartments, or cooling loss

• One fan assembly (motor and blade) as shown

• Disconnect power before starting any repair to avoid shock or injury
• Handle the blade and motor carefully to avoid bending or damaging the fan
• Verify mounting location and connector orientation before securing the assembly

This cooling fan motor spins the internal fan that moves air through the appliance to dissipate heat and protect sensitive components. Replacing a noisy, weak, or seized motor restores proper airflow and dependable operation.

• Drives the cooling fan to circulate cooling air within the cabinet
• Helps prevent overheating and thermal shutdowns of internal parts
• Restores airflow when the original motor is worn, noisy, or not turning
• Typical signs include no fan movement, unusual humming/squealing, reduced airflow, or the unit shutting off from heat

• Disconnect power (and gas, if applicable) before servicing; allow the appliance to cool completely
• Access the motor by removing the appropriate rear/top or control-panel cover for your model
• Note wire orientation; transfer the fan blade and any mounting parts from the original motor if required
• After installation, ensure the fan spins freely and verify proper airflow and quiet operation

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

Size: 5 inches x 7 3/4 inches.

The Door Latch Hook is an OEM replacement part for LG microwaves. Located internally on the door frame, this metal hook secures firmly into the microwave's door latch bracket when closed. As a common wear point, the hook can experience minor warping over many years of use.

Causes of a bad door latch hook include normal wear and tear, loss of tension, or deformation from frequent door opening and closing cycles long-term.

Symptoms of a bad latch hook include:

• Door that does not close fully or completely latch in place  
• Gaps forming in the door seal when shut
• Inability to achieve a tight, solid seal around the perimeter 
• Latch hook failing to grasp the bracket securely

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