Kenmore Microwave 721.80604500 (72180604500, 721 80604500) Parts

This replacement mounting screw secures panels and small appliance components to restore proper fit and prevent vibration or loose parts. A simple, direct replacement when the original fastener is missing or damaged. What it does:

• Secures panels, brackets, or small assemblies to keep parts aligned
• Stops rattling or vibration caused by loose or missing screws
• Restores normal fit where a stripped or corroded screw failed
• Matches the OEM fastener form for a correct, long-lasting fit

• Unplug the appliance or disconnect power before servicing
• Use the correct driver to avoid stripping the head
• Thread carefully and do not overtighten to prevent damage to threads or housing

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 turntable shaft (MH-8) connects the microwave's turntable motor to the glass tray hub so the tray spins for even heating. Replace it when the tray won't rotate, slips intermittently, or makes grinding/clicking noises.

• Couples the turntable motor to the tray hub to drive rotation
• Helps ensure even cooking and defrosting by keeping the tray moving
• Typical symptoms: tray not turning, intermittent/jerky rotation, grinding or clicking from the cavity floor
• Damage indicators: cracks, melted/rounded drive surfaces, or excessive wobble

• Disconnect power to the microwave at the plug or breaker before servicing
• Remove the glass tray and roller ring to access the shaft
• Lift the old shaft straight up; if stuck, access the turntable motor from below to push it out
• Align and press the new shaft fully onto the motor spindle; reassemble and test rotation

This thermostat is a temperature-sensitive safety switch used in LG microwaves. It monitors internal temperature and opens the circuit when overheating is detected to help protect components from heat damage.

• Monitors temperature at its mounting location inside the microwave
• Opens on overtemperature to interrupt power for safety
• Depending on model/location, a failed or open thermostat can cause no heat, the unit shutting off mid-cycle, or no power until it cools
• Helps prevent damage to the magnetron, cavity, and wiring due to overheating

• Unplug the microwave before service; the high-voltage capacitor can retain a dangerous charge
• Note wire positions, remove mounting screws, and install the new thermostat flat against the surface for proper heat sensing
• Reassemble and test; ensure vents and filters are clear to maintain proper airflow and prevent future overheating

This is a motor start/run capacitor that helps the appliance's motor start and run smoothly by supplying a brief boost of electrical energy. Replacing a failing capacitor restores reliable motor startup and operation. What it does:

• Provides the brief electrical surge needed to start and keep the motor running
• Commonly linked to motors that hum, fail to start, or run intermittently
• Helps prevent overheating from repeated start attempts when functioning properly
• Works with the appliance's start circuitry to ensure consistent performance

• Disconnect power to the appliance before accessing electrical components
• Discharge the capacitor and use insulated tools
• Observe polarity/terminal layout and secure connections to factory specifications
• Dispose of the old capacitor according to local electronic-waste regulations

The Door Latch Hook is an OEM replacement part for LG microwaves. Located internally on the door frame, this metal hook secures firmly into the microwave's door latch bracket when closed. As a common wear point, the hook can experience minor warping over many years of use.

Causes of a bad door latch hook include normal wear and tear, loss of tension, or deformation from frequent door opening and closing cycles long-term.

Symptoms of a bad latch hook include:

• Door that does not close fully or completely latch in place  
• Gaps forming in the door seal when shut
• Inability to achieve a tight, solid seal around the perimeter 
• Latch hook failing to grasp the bracket securely

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