What to do

1. Stop using the oven immediately if the door glass is cracked or shattered.
2. Carefully clean up any loose glass fragments, wearing gloves, and keep children and pets away from the area.
3. Do not attempt to operate the oven with damaged door glass, even if it still appears to close.
4. Check whether just the outer decorative panel or the inner heat-resistant panel is affected, since ovens often have multiple glass layers.
5. Contact an appliance parts supplier or technician for a replacement door glass panel or full door assembly specific to your model.
6. Avoid placing cold items directly against a hot oven door glass in the future to prevent thermal shock.
7. Have a technician install the replacement glass to ensure a proper, safe seal.
