The Fuse is an OEM component specifically designed for Bosch microwaves. It protects internal circuits and components from power surges or overloads that could cause damage. Proper functioning defends the appliance from electrical hazards.

Symptoms of a blown fuse can involve the microwave failing to power on or function after prior episodes of tripped internal safety mechanisms. Repeated events increase replacement needs.

Causes of a bad fuse involve normal wear under prolonged power cycling. However, significant power spikes pose greater fuse risks necessitating timely changes to warranty circuit integrity.  

Symptoms of a bad fuse include:

• Microwave fails to turn on or shows no response to controls
• Lightbulb does not illuminate during heating cycles
• Tripped circuit breakers occur frequently

This OEM Bosch part is also compatible with some Thermador, Blomberg, and Miele microwaves. Replace faulty fuses to restore appliance usability and safety.

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
