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 replacement microwave lamp restores the lighting you rely on to safely see food in the cavity or the cooktop below, depending on your model. Replace a burned-out bulb to bring back clear, convenient visibility while cooking.

• Provides illumination for the microwave interior or the cooktop beneath an over-the-range unit
• Common symptoms: light does not turn on with the door or during cooking
• Other signs of failure: dim, flickering, or visibly blackened bulb
• Restores visibility so you can monitor food and your workspace

• Disconnect power at the breaker or unplug the appliance before servicing
• Allow the area to cool; access location varies by model
• Handle capsule-style bulbs with gloves or a clean tissue; oils from skin can shorten bulb life
• Use only the lamp type and wattage specified for your model in the user manual or on the rating label

A direct-replacement circulating motor that moves air inside the refrigerator cabinet to help maintain even temperatures and consistent cooling. Replacing a worn motor restores airflow and can reduce warm spots and uneven cooling. What it does:

• Drives internal airflow to distribute cold air between compartments for more uniform temperatures.
• Restores circulation when a failed motor causes weak or no airflow.
• Common, safe-to-report symptoms: uneven cooling, warm spots in the fridge, the appliance running more than usual, or unusual humming/noise from the cabinet.
• Works with the appliance's wiring harness and mounting system to deliver continuous air movement while the cooling system runs.

• Always unplug the appliance before beginning service to avoid electric shock.
• Handle the motor and fan blades carefully to avoid bending or damage; keep fingers and tools clear of blades.
• Confirm correct connector orientation and secure mounting to prevent vibration or rubbing.
• After installing, power up briefly to verify the motor runs and the fan spins freely before reassembling panels.

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

This heater sheath is the metal housing that surrounds and protects the dryer's electric heating element, helping direct heated air into the drum for normal drying. Replaces a damaged or corroded sheath to restore safe, efficient heating. What it does

• Holds and shields the heating element assembly to prevent contact with other components
• Directs airflow around the heating element so the dryer can produce warm air
• Helps maintain proper element alignment and electrical insulation
• Common symptom: dryer runs but produces little or no heat
• Common symptom: visible damage, rust, or burn marks on the element housing

• One heater sheath (heating element housing) as shown

• Disconnect power (unplug or switch off breaker) before servicing to avoid electric shock
• Handle the heating element and terminals carefully; sharp edges may be present
• Inspect element, thermal fuse, and wiring while the cabinet is open; replace only confirmed faulty parts
