Kenmore Microwave 721.79152010 (72179152010, 721 79152010) 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.

The Door Latch Spring is a genuine OEM part for LG microwaves. As a key component of the microwave, the door latch spring is responsible for providing the tension needed to securely close and latch the microwave door. It works behind the scenes to ensure a tight seal when the door is shut.

Symptoms of a bad door latch spring include:

• The microwave door not closing or latching properly 
• Gaps appearing around the door seal when shut
• Difficulty opening and closing the door

Causes of a bad door latch spring can include wear and tear over time. Exposure to excessive door slamming can also place undue stress on the spring.

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

This is the glass turntable tray for the microwave cavity. It provides a stable, heat-resistant surface that rotates food for more even heating and reheating.

• Sits on the turntable support/roller and engages the center drive
• Helps promote even cooking by rotating food through the microwave energy
• Common failure signs: cracked or missing tray, wobbling during rotation, scraping noises, or uneven heating
• Replaces a damaged tray to restore safe, stable operation

• Unplug the appliance before servicing; allow interior to cool
• Remove the old tray, clean the support/roller, and seat the new tray on the center hub
• Ensure the tray sits flat and rotates freely before use
• Handle glass carefully to avoid chips or cracks

This holder assembly secures and guides the door latch components so the door closes firmly and the safety interlock switches engage. Replacing a worn holder restores reliable latching and helps the unit start consistently.

• Supports and aligns the latch mechanism within the door
• Ensures door hooks engage the interlock switches for safe operation
• Helps prevent a door that won't latch or pops open
• Common symptoms: unit won't start or shows a door error unless you press on the door

• Disconnect power at the breaker before service; microwaves contain high voltage even when unplugged
• Remove the door, separate the inner/outer panels, and transfer the latch holder
• Reassemble carefully, verifying smooth latch movement and proper door alignment
• Test door closure and operation before returning to service

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 molded resin cover restores a clean, finished look while protecting the underlying assembly. Use it to replace a cracked or missing cover so components stay shielded and properly secured during normal operation. What it does:

• Shields internal components and provides a finished appearance for the covered area
• Helps keep dust, grease, and debris away from internal parts as designed
• Replaces covers with broken tabs, cracks, warping, or missing sections
• Common symptoms include a loose/rattling panel, poor fit, or visible damage

• One resin cover

• Disconnect power to the appliance before servicing
• Remove any mounting screws and/or release tabs; note the orientation for reassembly
• Transfer reusable clips or hardware from the original cover if applicable
• Do not overtighten fasteners to avoid cracking the plastic

This replacement screw secures specified panels or components inside your appliance. Refreshing worn or missing hardware helps restore a tight fit, reduce rattling, and keep assemblies properly aligned for reliable performance.

• Provides secure fastening for brackets, panels, or internal assemblies
• Replaces stripped, rusted, or lost hardware
• Helps reduce vibration and rattling noises
• Symptoms include loose panels, shifting components, or a screw that won't tighten

• Disconnect power and allow any hot surfaces to cool before servicing
• Wear cut-resistant gloves and eye protection
• Match length and thread to the original; replace like-for-like
• Start threads by hand to avoid cross-threading; do not overtighten

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

• 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

• 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.
