The Switch is an OEM component specifically designed for Bosch microwaves. It controls critical heating elements and fan functions through the direct user interface. Seamless button response allows convenient operation.

Symptoms of a faulty switch involve non-responsiveness or inaccurate reaction to control presses. Opening from wear over extended usage risks compromised performance warranting replacement. 

Causes of a bad switch include normal degradation inhibiting smooth movements. Exposure to moisture-increasing interior corrosion necessitates a change to restore full functionality.

Symptoms of a bad switch include: 

• Microwave fails to start or prematurely stops cooking cycles  
• Inaccurate power levels result in uneven heating
• Inoperative special features like popcorn do not engage

This OEM Bosch part is also compatible with some Thermador, Blomberg, and Miele microwaves. Replace to maintain dependable command of essential microwave functions.
 

This switch is an electrical component that opens or closes a circuit inside your appliance. Replacing a worn or failed switch restores proper signaling to the control so the selected function responds reliably when actuated.

• Opens/closes an electrical circuit to send an on/off signal to the appliance's control or motor
• Enables the appliance to start, stop, or register a user input as designed
• Common symptoms: no response when pressed/activated, intermittent operation, feature stuck on/off, or error codes referencing a switch
• Resolves issues caused by heat, wear, moisture, or mechanical fatigue of the original switch

• Disconnect power at the breaker before servicing; verify power is off
• Note wire locations and take a photo; move connectors over one at a time to the new switch
• Do not force or bend terminals; replace any loose or heat-damaged connectors
• Restore power and test the function before final reassembly

This micro switch is a small, fast-acting on/off switch tripped by a mechanical lever or float to send a signal to the control. Replacing a worn microswitch restores accurate sensing so the appliance starts, stops, and runs when it should. What it does

• Senses the position of a linked mechanism (lever, float, latch) and opens/closes an electrical circuit
• Helps the control enable or disable functions only when conditions are correct
• Failure symptoms include intermittent operation, cycles that won't start, or a unit that keeps running until power is removed

• Disconnect power and, if applicable, shut off water before servicing
• Access the switch and note actuator orientation and terminal layout
• Move wires to the new switch one at a time to maintain correct placement; ensure tight connections
• Manually actuate the mechanism to ensure a positive "click" and proper operation before reassembly

• Replaces a burned-out or flickering bulb to eliminate dark or partially lit oven interiors
• Helps diagnose whether lack of light is due to the bulb
• Fits behind the oven light cover and provides general illumination of the cavity

• Turn off power and allow the oven to cool completely before replacing the lamp
• Remove the oven light cover or shield per your appliance instructions before swapping the bulb
• Avoid touching the glass with bare hands; use a clean cloth or gloves to prevent oils on the bulb
• Reinstall the cover securely and test the lamp; if it still does not light, check the fixture and power

This Faraday cage is the metal cavity shield that surrounds a microwave's cooking chamber to contain microwave energy and protect internal electronics. Replacing a damaged cage helps stop arcing and restores safe, even cooking performance. What it does:

• Shields and contains microwave energy inside the oven cavity to prevent leakage
• Protects internal components and control electronics from stray RF and interference
• Prevents arcing and sparking caused by holes, dents, or damaged shielding
• Helps restore even heating when cavity damage is the root cause of performance issues

• Disconnect power at the breaker before beginning any repair.
• Handle with care—edges may be sharp; use gloves and eye protection.
• Verify alignment and door latch/ seal fit after installation to ensure proper microwave containment.

• Replaces a worn, broken, or cracked lever that releases the door latch.
• Lets the door latch release properly so the door opens without excessive force or sticking.
• Works with the latch assembly to help ensure the door closes securely and operates smoothly.
• Addresses common symptoms such as a loose or unresponsive door handle, difficulty opening the door, or a lever that snaps.

• Disconnect power (and water, if applicable) before attempting any repair.
• Access may require removing the door trim or outer panel; basic hand tools are typically needed.
• Inspect surrounding latch components while replacing the lever and replace any damaged hardware.

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.
