Kenmore Microwave 721.64289301 (72164289301, 721 64289301) Parts

Microwave won't heat but runs normally? A failed magnetron is the likely cause. This part generates the microwaves that cook food. Moderate DIY repair.

Microwave won't heat or makes loud buzzing noise? The diode regulates magnetron current flow. Simple repair—test with multimeter for continuity.

This holder assembly secures the locker/latch mechanism in place so the door or access panel aligns and closes properly. Replacing a cracked or missing holder restores secure engagement and smooth, reliable operation. What it does:

• Supports and positions the locker/latch mechanism
• Maintains alignment for consistent latching and closing
• Common symptoms of a failed holder: loose latch feel, misalignment, door/panel not staying closed, or visible cracks/broken mounts
• Direct-fit replacement to restore proper support

• 1 holder assembly

• Disconnect power to the appliance before servicing.
• Access the locker area and retain any screws/clips; transfer any reusable hardware from the original holder as needed.
• Align the new holder with existing mounting points and tighten screws evenly—do not overtighten.
• Test latch engagement and door/panel operation before final reassembly.

Fix F4 error codes or sensor cook failures with this microwave humidity sensor. Restores automatic cooking cycles. Moderate DIY difficulty.

Microwave won't heat? A failing high-voltage capacitor disrupts the heating circuit. This part stores electrical energy for consistent operation.

Thermistor is a temperature-sensing replacement that monitors refrigerator and freezer temperatures so the control board can regulate cooling. Replacing a faulty thermistor restores accurate temperature readings and helps stabilize cooling performance. What it does:

• Senses interior/evaporator temperature and sends a signal to the control board for temperature regulation.
• Helps prevent erratic cooling, long run-times, or inconsistent compartment temperatures when operating correctly.
• Faulty thermistors can contribute to excessive frost, failed defrost cycles, or compressor cycling issues.
• Use when the existing sensor fails to report correct temperatures or the part number matches.

• Always disconnect power to the appliance before servicing to avoid shock or damage.
• The sensor is typically mounted on or near the evaporator or inside a cabinet wall; access may require removing panels or covers.
• Handle the sensor and wiring harness gently; avoid pulling on wires or bending the sensor element.

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 Fan Blade is an OEM part for LG microwaves. It is a critical component designed to circulate air within the microwave, aiding in heat dissipation and ensuring even cooking. 

Fan blades in microwaves can suffer from wear, imbalance, or damage due to regular use or accumulation of debris. A malfunctioning fan blade can lead to inadequate ventilation, affecting the microwave's cooking efficiency and potentially causing overheating.

Symptoms of a bad fan blade include:

• Unusual noises during operation, such as rattling or buzzing, indicate a loose or damaged blade.
• The microwave overheating or shutting off prematurely.
• Inconsistent cooking or hot spots in food suggest poor air circulation.
• The fan not starting, or stopping unexpectedly during use.
• Visible signs of damage or wear on the blade.

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

This 4.0x16mm tapping screw secures trim, panels, and brackets on ranges and microwaves. Replace missing, stripped, or damaged screws during repair.

Replace your microwave door seal cushion to restore proper door closure and prevent heat loss. Essential when the seal is worn, cracked, or loose. Verify fit with your model number before ordering.

Microwave won't start or runs with door open? Failed door switch prevents safe operation. Simple DIY fix with basic tools in under 30 minutes.

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.

Leveling leg that installs at the base of your range to provide stable, adjustable support. Replace if the foot is cracked, broken, or missing.

Self-threading screw secures microwave panels and components. Replaces stripped, missing, or damaged screws to restore secure fits and eliminate rattles.

A circular lug designed to join a stripped wire to a threaded terminal for a secure electrical connection. Helps restore reliable contact at terminals and reduces the chance of intermittent power or arcing at connection points. What it does:

• Provides a strong mechanical and electrical connection between a wire and a screw or bolt terminal.
• Helps prevent loose connections that can cause intermittent operation, sparking, or overheating.
• Commonly used where a ring-style termination is required for safe, stable wiring.
• Works with properly sized wire and fasteners to maintain consistent conductivity.

• Always disconnect power to the appliance before inspecting or replacing electrical parts.
• Use the correct lug size and gauge for the wire and terminal; crimp or solder per manufacturer recommendations.
• Tighten terminal hardware to the appliance manufacturer's specified torque; avoid over-tightening which can damage the lug or terminal.
• If wiring insulation or the terminal is damaged or corroded, replace the affected components rather than reusing them.
