What to do
- Turn off and let the oven cool completely before inspecting.
- Open the door and run your hand along the gasket to feel for flat spots, tears, or looseness.
- Check that racks are pushed in fully and nothing is wedged between the door and the oven frame.
- Close the door gently and look for gaps, especially at the top corners.
- With the door open, check both hinges for looseness by gently wiggling the door side to side.
- If the gasket looks worn or torn, it's a straightforward DIY replacement that clips or screws into place.
- If hinges are bent or the door doesn't sit level even with a good gasket, call a technician to assess the hinge assembly.
