Bosch Oven: turns off when door is opened
What is this symptom?
If your Bosch oven turns off immediately when the door is opened, it could be a sign of a malfunctioning door safety switch or an issue with the control board. This symptom indicates that the oven is not functioning properly, potentially interrupting your cooking process. Understanding the underlying causes can help you address the issue effectively.
Important Tips for Bosch Models
- Bosch ovens use a door position detection switch as part of their safety design; faults in this switch are a frequently mentioned cause for power cut-offs on community repair sites.
