Malfunctioning Door Switch
To test the door switch, you'll need to carefully inspect the switch and the corresponding relay on your microwave's control panel. If the switch is malfunctioning, replacing it might resolve the issue.

This integral component manages all the microwave's functionalities, including power distribution and user interface. If it malfunctions, it can cause erroneous or unexpected behavior, like turning off the microwave.
Testing the main control board typically requires specialized tools and expertise. If you suspect this component is causing the issue, it's wise to consult a professional technician for diagnosis and repair.
Troubleshooting and Fixing the Issue
