Kenmore 72180043700 Parts

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 high-voltage transformer steps household AC up to the level the magnetron needs to generate microwave energy. Replace a failing transformer to restore reliable heating when the unit runs but food remains cold.

• Steps up line voltage to the high voltage required by the magnetron
• Works with the high-voltage capacitor and diode to create microwave energy
• Failure can cause running but no heat, loud humming/buzzing, burning odor, or visible overheating
• Shorted windings can blow the internal fuse or trip a breaker

• Unplug the microwave; high-voltage components can retain a dangerous charge—properly discharge the HV capacitor.
• Remove the outer cabinet, label wire locations, and disconnect leads carefully. Transfer any mounting hardware/brackets and secure the transformer firmly.
• Verify all connections are tight and routed correctly; reassemble and test with a cup of water. Do not operate the microwave empty.

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

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 mechanical charcoal refrigerator filter helps reduce food and fridge odors for fresher-smelling compartments. It's a direct-fit replacement that restores odor-absorbing capability so your fridge interior smells cleaner. What it does

• Adsorbs and traps common food and household odors to reduce smells in the fridge
• Helps prevent odor transfer between compartments and stored foods
• Restores the intended odor-control function when the original filter is spent or clogged
• Works as a simple replaceable cartridge in compatible LG refrigerator filter housings

• One mechanical charcoal refrigerator filter cartridge

• High-level replacement: remove the old filter cartridge and snap or twist the new cartridge into the filter housing per the refrigerator manual
• Follow the refrigerator manufacturer's instructions for alignment and secure seating to avoid leaks or loss of function
• Disconnect power or follow any appliance-specific safety steps recommended by the manufacturer before servicing
• Dispose of the used filter per local regulations for household waste

This replacement lamp assembly restores interior illumination so you can see the appliance cavity clearly and safely. It fits the original mounting and electrical connections for a direct swap. What it does

• Replaces a burned-out, flickering, or dim interior lamp so you can inspect food and parts easily
• Provides the correct shape and connector to match the appliance's original lamp location and mounting
• Helps eliminate intermittent lighting caused by a damaged lamp or failed lamp connection
• Restores normal light output for safe loading and unloading

• Disconnect power to the appliance before starting any repair
• Allow the appliance and old lamp to cool completely before handling
• Handle the lamp by its base or use gloves to avoid oil contamination on the bulb
• Follow the appliance's service manual or OEM diagram for correct removal and installation

The Microwave Turntable Motor is an OEM replacement part for LG over-the-range microwaves. This motor is responsible for powering the turntable inside the microwave cavity, ensuring even heating and cooking of food items.  

Symptoms of a bad motor include: 

• The turntable not spinning or turning intermittently
• Loud buzzing or grinding noises coming from the microwave interior
• The turntable spinning but not evenly or at the proper speed
• Smoke or burning smells coming from the microwave

Causes of a bad motor can include normal wear and tear over extended use, residue or debris buildup interfering with operation, or failure of internal motor components.

The Door Latch Housing and Interlock Switch Assembly is an OEM replacement part for LG microwaves. It consists of the protective door latch housing casing along with the two-door switches and interlock switch.

The interlock switch prevents microwave energy from being generated inside the oven when the door is open. It shuts off all power once a faulty seal is detected between the door and cavity.

Symptoms of issues can include:

• Microwave failing to turn on or cook with the door open
• Sparking or arcing seen near the door seal or frame
• Error codes displayed related to interlock detection faults

Compatible models include some GE, Kenmore, and Samsung units using matching door designs sourced from LG.

This bracket assembly provides a secure mounting point for internal components, keeping parts aligned and stable for reliable appliance operation. It restores proper support where a worn or broken bracket causes rattling or misalignment. What it does:

• Secures and supports internal components or panels to prevent movement and vibration
• Restores proper alignment for parts that have shifted due to a damaged bracket
• Helps eliminate rattling, knocking, or loose-panel noises caused by broken mounting points
• Maintains spacing that ensures connected parts operate smoothly

• Disconnect power before beginning any repair to avoid electrical shock
• Inspect surrounding fasteners and mounting surfaces; replace any stripped screws or damaged clips
• Use appropriate hand tools; avoid over-tightening fasteners which can crack plastic parts
