Customer Questions and Answers for Oven Door Gasket (30-In) by Bosch

The oven door gasket is the heat-resistant seal around the 30-inch oven cavity. It helps the oven reach and hold temperature, preventing heat and steam leaks, and replaces a worn or damaged seal for consistent baking results.

• Seals the door-to-cavity gap to limit heat and moisture loss
• Restores proper door compression to help maintain accurate temperatures and normal preheat times
• Replaces gaskets that are torn, frayed, flattened, brittle, or stretched
• Common symptoms: hot air or steam escaping at door edges, temperature fluctuations, longer cook times, or a door that no longer closes snugly

• Disconnect power and allow the oven to cool completely before servicing
• Open the door and remove the old gasket, noting seam orientation and where the ends seat
• Clean the mating surfaces; install the new gasket with the seam at the bottom center, seating the ends fully into the factory holes/retainers without overstretching
• Close the door and check for uniform contact around the perimeter
