Parts for Kenmore 721.80833500 (72180833500, 721 80833500): Interior Parts

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 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 synchronous motor drives the microwave's glass turntable at a steady speed so food rotates for more even heating. Replace a weak or seized motor to restore smooth tray movement and consistent cooking performance.

• Provides slow, consistent rotation of the glass tray during cook cycles
• Helps promote more even heating by turning food under the magnetron
• Typical symptoms: turntable not turning, intermittent or jerky rotation, or humming without movement
• Located beneath the oven cavity, driving the coupler from below

• Disconnect power before servicing; microwaves contain high-voltage components that can retain a dangerous charge
• Access is typically from the bottom; remove the bottom cover and mounting screws to reach the motor
• Transfer the two wires one at a time to the new motor and ensure the shaft fully engages the turntable coupler
• Reinstall the cover and test rotation first without the glass tray, then with the tray and support

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 cooling fan motor spins the internal fan that moves air through the appliance to dissipate heat and protect sensitive components. Replacing a noisy, weak, or seized motor restores proper airflow and dependable operation.

• Drives the cooling fan to circulate cooling air within the cabinet
• Helps prevent overheating and thermal shutdowns of internal parts
• Restores airflow when the original motor is worn, noisy, or not turning
• Typical signs include no fan movement, unusual humming/squealing, reduced airflow, or the unit shutting off from heat

• Disconnect power (and gas, if applicable) before servicing; allow the appliance to cool completely
• Access the motor by removing the appropriate rear/top or control-panel cover for your model
• Note wire orientation; transfer the fan blade and any mounting parts from the original motor if required
• After installation, ensure the fan spins freely and verify proper airflow and quiet operation

This thermostat controls oven/dryer temperature by opening or closing its contacts as the appliance reaches set temperatures, helping maintain safe and consistent operation. Replaces a worn or failed thermostat to restore proper temperature regulation. What it does:

• Senses temperature and interrupts heating when limits are reached to prevent overheating
• Re-establishes heating when temperature falls, maintaining normal cycle performance
• Commonly installed when an appliance won't heat, overheats, or cycles erratically
• Works as a direct replacement for the OEM thermostat designed for compatible LG units

• One thermostat

• Disconnect power to the appliance before starting any repair to avoid shock or injury
• Note wire locations or take a photo before removing wiring; reconnect wires to the same terminals
• Use a multimeter to verify thermostat continuity and correct operation before and after replacement
