Kenmore Microwave 721.62212200 (72162212200, 721 62212200) Parts

The Microwave Door Switch is an OEM replacement part for LG countertop microwaves. It monitors the door position electrically to prevent unsafe oven operation if ajar. 

Symptoms of a bad door switch include:

• Inability to start or pause a cooking cycle unless securely latched  
• Error messages about the door being open
• Inconsistent detection of open/closed door positions
• Unreliable contact functioning after extended use

Causes involve normal wear of electrical contacts and internals through many open/close uses. Exposure to moisture intrusion from spills may potentially damage sensitive switch circuitry over time as well.

This genuine LG replacement switch is also compatible with Sears/Kenmore microwaves.

The Magnetron is an OEM part for LG microwaves. It is responsible for generating the microwaves that cook or heat the food inside the appliance. The magnetron converts electrical energy into microwave radiation, ensuring efficient and even heating.

Causes of a bad magnetron can include prolonged use, electrical surges, or overheating. Over time, these factors can lead to the magnetron wearing out or failing completely.

Symptoms of a bad Magnetron include:

• The microwave not heating food
• Strange noises during operation
• Burning smell or smoke
• The microwave shutting off unexpectedly

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

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 door latch assembly engages the interlock switches when the microwave door closes, keeping the door securely shut. Replacing a worn latch restores safe door engagement and allows the oven to operate only when properly closed.

• Hooks into the cabinet strike to hold the door closed
• Actuates the interlock switches to permit heating
• Helps resolve: door won't latch or stay shut, "Door/Open" error messages, unit won't start unless the door is pressed
• Replaces a visibly cracked, worn, or broken latch

• Unplug the microwave before servicing; microwaves contain high-voltage components—work only on the door, not inside the cabinet
• Remove the inner door trim to access the latch; note orientation and transfer any clips/hardware as found
• Inspect the door strike and hinges for wear; misalignment can prevent proper latching
• After reassembly, verify smooth door closure and that the oven will not run with the door open

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

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
