This oven door gasket or door seal is used for ranges and ovens. This part works as a protective seal between the oven door and the opening of the oven. The seal traps heat and prevents it from escaping when the oven door is closed, for best results when cooking or baking. If your oven door gasket is ripped, damaged, or you find heat escapes your oven door, then it is best to replace the gasket to solve the problem. Remember to unplug your appliance from the power source before installing. For installation instructions, refer to the manual provided by the manufacturer.
