To reset the door lock on a Frigidaire oven, you can follow these steps:
1. Press the "Clear/Off" button on the oven's control panel.
2. Wait for a few seconds to allow the oven to power down.
3. After the waiting period, press and hold the "Clear/Off" button again for approximately 3-5 seconds.
4. Release the button when the door lock mechanism disengages, and the oven display resets.
5. The oven door lock should now be reset, and you should be able to open the oven door.
If the door lock does not reset or you encounter any difficulties, refer to the oven's user manual or contact Frigidaire customer support for further assistance.
