Customer Questions and Answers for Door Switch by Bosch

The Door Switch is an OEM part for Bosch microwaves. This part ensures that the microwave oven does not operate unless the door is securely closed, a critical safety feature to prevent exposure to microwave radiation. The switch interacts with the microwave’s control system, signaling when the door is closed and it's safe to initiate cooking. 

Causes of a bad Door Switch can include mechanical wear and tear from regular use, leading to a failure to engage properly.  

Symptoms of a bad Door Switch in a microwave include:

• The microwave not starting or operating when the door is closed.
• Intermittent operation or sudden stopping of the microwave during use, suggesting the door switch is not consistently engaged.
• The microwave continuing to operate when the door is opened, indicating a serious safety concern.

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