Kenmore Microwave 721.89950590 (72189950590, 721 89950590) Parts

The Damper Bracket is an OEM component for LG microwaves. Located inside the microwave cavity above the wave stirrer, this bracket holds the position of the damper assembly that helps distribute heat evenly during cooking. The bracket measures approximately 12” by 5”.

Symptoms of a bad damper bracket can include:  

• Hot or cold spots developing within the microwave cavity
• Looseness in the damper assembly fit
• Reduced heat circulation leading to uneven cooking

Causes typically consist of cracking over long-term heat exposure. Repeated opening/closing of the damper may also weaken attachment points on the bracket.

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

The Damper is an OEM component for LG microwaves. Located within the cooking cavity, it regulates airflow and safely vents steam escaping heated foods. 

Causes of a faulty damper can involve standard wear and exposure accepting steam and condensation release. Food or liquid particles drying within tracks also threaten eventual adhesion issues restricting travel if left unaddressed between cleanings.

Symptoms of a damaged or defective damper include:

• Inability to adequately vent excess moisture from heating  
• Potential messes spilling beyond the microwave frame  
• Grating sounds or squeaks emitting during cooking
• Flaps possibly stuck inhibiting steam circulation 

This damper is also compatible with Kenmore microwaves as well.

The Light Bulb is an OEM part for LG microwaves. It provides illumination inside the microwave oven, allowing users to monitor the cooking process and check the condition of the food without opening the door.

Causes of a bad light bulb can include normal wear and tear, electrical surges, or damage due to impact or overheating. Over time, the filament inside the bulb can burn out, or the bulb itself can become loose or disconnected.

Symptoms of a bad light bulb include:

• The microwave interior light not turning on
• Flickering or dimming of the light
• Intermittent lighting during operation

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 factory fastener secures appliance panels and components. Use it to replace a missing, stripped, or corroded screw so brackets, covers, and assemblies stay tight and properly aligned, helping reduce vibration and rattling.

• Secures panels, brackets, and internal components in their proper positions
• Replaces missing, worn, or cross-threaded hardware
• Helps eliminate vibration and rattling from loose parts
• Supports proper alignment of covers and assemblies

• Disconnect power to the appliance before servicing; allow any moving parts to stop
• Match this screw to the location shown in your model's parts diagram
• Start threads by hand to avoid cross-threading, then tighten snugly with the correct driver
• Do not overtighten to prevent stripping threads or cracking plastic bosses

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

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.

Size: 5 inches x 7 3/4 inches.
