Kenmore Microwave 721.68360790 (72168360790, 721 68360790) 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.

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

A small replacement fastening nut used to secure components on LG appliances. Replacing a worn or missing nut restores a secure fit and helps eliminate looseness or rattling for reliable operation. What it does

• Fastens and secures mating parts or hardware on appliance assemblies
• Stops movement that can cause rattling, vibration, or misalignment
• Useful when a nut is stripped, lost during service, or damaged
• Helps maintain safe, stable operation of the repaired area

What's included One nut as shown Install notes

• Disconnect power and water before servicing the appliance
• Verify the nut matches the original by thread, size, and profile before installation
• Hand-thread first to avoid cross-threading, then tighten with the correct tool; avoid overtightening
• Keep small parts away from children and pets during repair

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 Blade is an OEM part for LG microwaves. It is a critical component designed to circulate air within the microwave, aiding in heat dissipation and ensuring even cooking. 

Fan blades in microwaves can suffer from wear, imbalance, or damage due to regular use or accumulation of debris. A malfunctioning fan blade can lead to inadequate ventilation, affecting the microwave's cooking efficiency and potentially causing overheating.

Symptoms of a bad fan blade include:

• Unusual noises during operation, such as rattling or buzzing, indicate a loose or damaged blade.
• The microwave overheating or shutting off prematurely.
• Inconsistent cooking or hot spots in food suggest poor air circulation.
• The fan not starting, or stopping unexpectedly during use.
• Visible signs of damage or wear on the blade.

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

This replacement screw fastens panels and components in your appliance, keeping them secure and aligned. Replace stripped, rusted, or missing hardware to stop rattles and ensure assemblies stay tight through everyday use.

• Secures covers, brackets, and internal assemblies at the specified mounting points
• Helps correct looseness or misalignment after a fastener is lost or stripped
• Can reduce rattling or vibration noises caused by loose fasteners
• Restores proper fit of panels or trim pieces

• Disconnect power to the appliance and shut off water or gas before servicing
• Match length and thread to the original fastener before installation
• Start threads by hand to avoid cross-threading; tighten only until snug to prevent damage
• Reuse any washers, spacers, or threadlocker originally installed at this location

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.

A flat washer used with the appliance's fastening hardware to distribute load and reduce wear. Helps maintain secure connections and prevents damage to mating surfaces for reliable operation. What it does:

• Provides an even bearing surface for bolts or screws to prevent pull-through
• Reduces friction and wear between fasteners and housing parts
• Helps keep fasteners tight and resists loosening from vibration
• Commonly used where a smooth, protective spacer is needed

• Verify correct location and orientation before reassembly
• Use manufacturer-recommended fasteners and torque specifications
• Power off and unplug the appliance before accessing internal components
