Microwave won't power on? A blown fuse is often the culprit. This protective component prevents electrical damage from power surges. DIY repair in 1-2 hours.

Light not coming on when door opens or during cooking? This interior light bulb restores visibility inside your microwave or oven cavity.

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.

This electrical switch restores reliable on/off signaling for a specific function in your appliance. Replacing a worn or burned switch helps ensure consistent activation and dependable operation of the affected feature. What it does

• Opens and closes an electrical circuit when actuated to start/stop a function
• Sends a clear signal to the control or power circuit for the selected operation
• Failure symptoms include the function not engaging, intermittent operation, or no response when actuated
• Visual clues can include darkened, melted, or loose terminals and an inconsistent click/feel

• 1 switch

• Disconnect power to the appliance before servicing; shut off water or gas if applicable
• Note wire positions and transfer connectors one at a time to the correct terminals
• Seat terminals fully and secure the switch without overtightening; avoid bending the actuator
• Test operation before final reassembly to ensure proper engagement

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.

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.

Microwave won't heat or shuts off unexpectedly? The thermal relay disconnects power when temperatures exceed safe limits. Protects against overheating damage.

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.

This control board manages all microwave functions including power levels, timing, and cooking modes. It processes user inputs and controls the magnetron, turntable, and display operations. Replace this board if your microwave display is blank, buttons don't work, or cooking functions operate erratically.

This is a round push button located on the microwave control panel that activates the door release mechanism. It allows the door to pop open when pressed. Replace this button if it is cracked, stuck, or no longer engages the door latch properly when pushed.

This small drive motor rotates the turntable plate inside the microwave to ensure even heating of food. It connects to the turntable coupler beneath the glass tray and spins at a slow, steady speed. Replace this motor if the turntable stops rotating, turns intermittently, or makes grinding noises during operation.

This is a humidity sensor that detects steam levels inside the microwave cavity during cooking. It communicates moisture readings to the control board, allowing auto-cook and sensor-reheat functions to determine when food is done. Replace this sensor if your microwave's auto-cook cycles run too long or too short, or if sensor cooking modes no longer work properly.

Flat metal washer distributes load under nuts and bolts in your oven. Replace when worn, missing, or damaged to maintain proper alignment. Verify fit.

This spacer positions and secures components inside the appliance to maintain proper alignment and prevent contact or vibration. It's a small but important hardware piece for stable, quiet operation. What it does:

• Creates a precise gap between adjoining parts to ensure correct alignment during operation
• Prevents panels and components from rubbing or vibrating against each other
• Helps maintain consistent fit of assemblies after repairs or reassembly
• Can reduce noise caused by loose or misaligned parts

• One spacer

• Disconnect power (and water, if applicable) before beginning any repair
• Remove surrounding panels or components as needed to access the spacer location
• Note orientation and placement during removal so the replacement installs the same way
• Handle small hardware carefully; use magnetic tray to keep fasteners/parts organized

This small plastic clip secures internal components or wiring to the appliance chassis to prevent rubbing, movement, or noise. Replacing a worn or broken clip restores secure routing and reduces vibration-related sounds. What it does:

• Holds wiring harnesses or small parts in place to prevent chafing and wear
• Stops loose components from shifting during operation and causing rattles
• Helps maintain correct component alignment for reliable performance
• A broken or missing clip can allow wires or parts to contact moving pieces or hot surfaces

• Disconnect power to the appliance before starting any repair
• Clip typically presses into a matching slot or snaps over the component; no special tools usually required
• Handle small parts carefully; retain any removed fasteners for reuse
• If routing or mounting points are damaged, inspect surrounding parts for wear and replace as needed

This is an electrical noise filter installed inside the microwave to suppress electromagnetic interference generated during operation. It helps prevent the microwave from causing static or disruption to nearby electronics. Replace this filter if the microwave trips breakers, fails to start, or causes interference with other household devices.
