This is a door interlock switch that detects whether the microwave door is properly closed before allowing the unit to operate. It is a critical safety component that prevents the microwave from running with the door open. Replace this switch if the microwave does not start when the door is shut, stops mid-cycle, or blows a fuse when the door is closed.

Fix a microwave or oven that won't start or respond to controls with this switch replacement. Opens and closes circuits to restore reliable operation.

Replacement housing cover for microwaves and ovens. Closes and protects internal openings. Restores secure fit when original is cracked, missing, or warped.

Glass turntable tray for microwaves. Provides a stable, food-safe rotating surface for even heating. Replace your cracked, chipped, or missing tray.

Turntable won't spin or makes grinding noises? This motor drives the glass tray for even heating. Moderate DIY repair; requires removing bottom cover.

The Cooking Tray is an OEM part for Bosch microwaves. As the centerpiece of the microwave, the cooking tray ensures even cooking by rotating food items during the cooking cycle. It supports dishes and rotates continuously to evenly distribute microwave energy throughout recipes.

Causes of a bad cooking tray can include wear and tear due to extended use over time. Food splatter or spills left inside the microwave may damage or corrode the tray. Accidental dropping or cracking of heavier dishes placed on the tray can also cause issues.

Symptoms of a bad cooking tray include:

• The tray not spinning or rotating properly during cooking
• Unevenly or partially cooked food
• Loud grinding or scraping noises coming from the tray
• Cracks or breaks visible in the plastic surface

This genuine OEM Bosch part is also compatible with Thermador, Gaggenau and select Kenmore models.

This is a high voltage diode wire assembly used in the microwave's power circuit. It works with the capacitor and magnetron to convert electrical current and generate microwave energy for cooking. Replace this part if the microwave runs but does not heat, or if the diode has visibly burned or shorted out.

This fixed thermostat protects the appliance by opening the circuit when excessive heat is detected. Replacing a failed or weak thermostat restores reliable over-temperature protection and helps prevent heat-related shutdowns.

• Opens the circuit if the protected area overheats to help prevent damage to components
• Helps with symptoms like unexpected shutdowns during operation or no power after overheating
• Can be the cause when the unit only runs again after cooling down
• Helps maintain safe operating temperatures around heat-sensitive parts

• Disconnect power before servicing; some appliances contain high-voltage components
• Access location varies by model; note wire positions before removal and transfer one lead at a time
• Reuse existing mounting hardware; ensure firm terminal connections and correct orientation
• After replacement, confirm proper airflow/venting and normal operation

Oven won't start or stop correctly? A faulty micro switch prevents proper sensing of linked mechanisms. This switch restores accurate control signals.

Fix a microwave door that won't pop open when you press the button. This door release lever restores smooth latching action for easy everyday use.

Replace your cracked or broken microwave glass turntable tray to restore even heating. This rotating tray sits on the roller ring for smooth operation.

Fix a microwave that won't heat with this high voltage capacitor. Stores electrical charge to power the magnetron. Replace if heating has stopped.

Microwave not heating or sparking inside? This high voltage capacitor stores power for the magnetron. Common repair taking 30-45 minutes with care.

Color: Citrine white. Size: 4.5 oz. can. Acrylic appliance aerosol can spray paint.

Mounting screw secures panels, brackets, and trim to the appliance frame. Replace if screw is stripped, missing, or damaged to restore secure fastening.

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
