Kenmore Microwave 721.68100790 (72168100790, 721 68100790) Parts

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 rivet assembly fastens panels, brackets, or covers inside the microwave cabinet. Replacing a damaged or missing fastener restores a tight fit, reduces vibration noise, and keeps mounted components properly aligned.

• Secures panels, brackets, or covers to the cabinet for a stable fit
• Use when a rivet is cracked, missing, or no longer holds
• Can help resolve rattling, buzzing, or loose panel movement
• Maintains proper alignment and support of mounted parts

• Disconnect power before servicing; support and remove over-the-range/built-in units for safe access.
• Microwaves contain a high-voltage capacitor that can retain a dangerous charge—service should be performed by qualified personnel.
• Reinstall using existing mounting holes; ensure the rivet is fully seated and secure.
• Wear cut-resistant gloves and eye protection to avoid injury from sharp metal edges.

This truss head tapping screw secures panels, brackets, and covers in your appliance. Replacing a missing or damaged fastener restores a snug fit, reduces vibration, and helps keep components properly aligned for reliable performance.

• Provides low-profile holding power; wide truss head helps secure thin panels and trim
• Replaces lost, stripped, or corroded screws at the original mounting points
• Helps eliminate rattling, vibration, or loose handles/covers
• Addresses situations where a screw will not tighten or backs out during use

• Disconnect power; shut off water/gas if applicable before servicing
• Align parts and hand-start threads to avoid cross-threading
• Tighten until snug; do not overtighten to prevent stripping
• If the receiving hole is damaged, for repair before installing the new screw

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 truss head tapping screw secures interior panels and small components on compatible appliances, restoring proper fit and stopping rattles or loose trim. It's a direct hardware replacement for a single mounting point. What it does:

• Fastens panels, brackets, and trim where a low-profile truss head is required
• Replaces missing or stripped screws that cause rattling or loose parts
• Provides a secure hold by forming threads in sheet metal during installation
• Useful for repairing cosmetic or functional panel alignment issues

• Disconnect power before working on any appliance to avoid shock or injury
• Use the correct sized Phillips or Torx driver to prevent cam-out or screw damage
• Start straight and thread slowly; do not overtighten to avoid stripping sheet metal
• Replace only with the exact part number for best fit and performance

This door release lever links the microwave's push-button to the latch mechanism so the door unlatches and opens smoothly. Replacing a worn or broken lever restores consistent, reliable button-operated door opening. What it does

• Transfers motion from the door open button to the latch hooks to release the door
• Helps ensure smooth, consistent door opening with each press
• Common symptoms: door won't open when pressing the button, button feels loose or sticks, intermittent opening, or broken plastic fragments near the button area

• 1 door release lever

• Disconnect power before servicing; microwaves contain high-voltage components
• If over-the-range, support or remove the unit to access internal components safely
• Remove the outer cover/control panel to reach the latch area; note lever orientation before removal
• After reassembly, verify the button action and door opening/closing before restoring power

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 replacement latch secures the appliance door or lid so it closes and engages reliably, helping the unit run and maintain proper operation. Ideal when the door won't stay shut or the appliance won't start. What it does:

• Secures the door/lid to the cabinet so the appliance can close properly
• Engages with the strike/keep to allow door-switch or lock mechanisms to operate
• Helps prevent leaks and heat loss caused by a door that won't seal
• Common symptom: appliance won't start or won't complete a cycle because the door fails to engage

• One latch

• Disconnect power (and water for washers) before starting any work
• Remove the access panel or door trim to reach the latch; use basic hand tools
• Check and adjust door alignment so the latch and strike meet squarely
• Test the door operation and run a short cycle to ensure reliable engagement

This thermostat controls refrigerator temperature to help maintain proper cooling and prevent spoilage. It replaces a failed or inaccurate temperature control to restore consistent operation. What it does:

• Senses internal temperature and signals the compressor to cycle on/off
• Helps keep food at steady, safe temperatures when functioning correctly
• Commonly replaces thermostats that cause warm temperatures or inconsistent cooling
• Works as a direct replacement when matching the OEM part number

• Always disconnect power to the appliance before servicing to avoid shock or injury
• Handle the sensor and terminals carefully; avoid bending or damaging components
• Basic hand tools are typically required; follow your model's service manual for exact instructions

This magnetron is the high-voltage microwave tube that generates the microwave energy used to cook and reheat food in your oven. Replacing a failing magnetron restores heating performance when the rest of the microwave system is functioning. What it does:

• Generates microwave energy that heats food inside the oven cavity
• Common symptom: unit powers on but does not heat
• May also cause loud humming, burning smell, or arcing when failing
• Works with the oven's high-voltage circuit and waveguide to deliver even cooking

• One magnetron

• High-voltage component — disconnect power and discharge the capacitor before service
• Avoid touching terminals or the ceramic insulators; handle by mounting brackets
• Verify other high-voltage components (diode, capacitor, transformer) and seals to ensure safe operation
