How to Repair an Oven Seal

A loose or broken oven door seal can prevent an oven from fully heating or cause the oven to heat unevenly. The door gasket should be tight and secure all the way around the oven door. If there is heat escaping from the door, the door seal may need to be replaced. Replacing a faulty door seal will allow the oven to heat more quickly and will help ensure that food cooked in the oven is cooked evenly and fully. Different models of ovens may have variations on how the seal will need to be installed, but the basic steps will be the same for most units.
