Kenmore Microwave 721.69109990 (72169109990, 721 69109990) 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 synchronous turntable motor rotates the glass tray inside your microwave to help food heat evenly. Replace it to restore smooth, consistent rotation if the tray has stopped turning, stalls intermittently, or makes unusual noises from the base.

• Drives the turntable via the center coupler to rotate the glass tray at a steady speed
• Promotes even exposure to microwave energy for more uniform heating
• Typical failure symptoms: tray won't turn, rotates only intermittently, or emits grinding/buzzing sounds from underneath
• If power reaches the motor but it doesn't run, the internal windings or gear set may be seized

• Disconnect power to the microwave before servicing
• If mounted over a range, remove the unit from the cabinet with assistance
• Access is typically from the bottom panel; note wire positions and shaft orientation before removal
• After installation, briefly test rotation before full reassembly; inspect the coupler and support for wear

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 replacement microwave lamp restores the lighting you rely on to safely see food in the cavity or the cooktop below, depending on your model. Replace a burned-out bulb to bring back clear, convenient visibility while cooking.

• Provides illumination for the microwave interior or the cooktop beneath an over-the-range unit
• Common symptoms: light does not turn on with the door or during cooking
• Other signs of failure: dim, flickering, or visibly blackened bulb
• Restores visibility so you can monitor food and your workspace

• Disconnect power at the breaker or unplug the appliance before servicing
• Allow the area to cool; access location varies by model
• Handle capsule-style bulbs with gloves or a clean tissue; oils from skin can shorten bulb life
• Use only the lamp type and wattage specified for your model in the user manual or on the rating label

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 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
