How to Tell If Your Oven Seal Needs Replacing

The oven door seal is a small but crucial part of your appliance that ensures even cooking and energy efficiency. Over time, heat and wear can cause it to lose flexibility or tear, letting hot air escape during cooking.

Common Signs Your Oven Seal Is Failing

Heat escaping from the oven door during use.
Uneven cooking or longer cooking times.
Visible cracks, splits, or flattening in the seal.
Food residues or burnt marks around the oven door frame.
The oven light flickers or stays on when the door is closed.

💡 Quick Tip

Close the door on a sheet of paper. If you can pull it out easily, the seal isn’t tight enough.

Why It Matters

A faulty seal means your oven must work harder to maintain temperature, wasting energy and affecting cooking results. Replacing the seal helps maintain consistent heat, reduces electricity use, and extends your oven’s lifespan.

Note: If your oven is part of a built-in setup, you can find replacement-ready models in our CATA Single Ovens range.

How to Replace an Oven Seal

Most seals can be removed without tools — they’re held by hooks or clips. Simply pull the old one out and press the new seal into the same slots, ensuring it fits snugly around the frame.

If your oven still leaks heat after replacing the seal, you may have a warped door or hinge issue. In this case, it’s worth seeking a professional repair.
