Using your Chef single - side oven door seal is easy. First, make sure your oven is turned off and cooled down. Carefully remove the old seal from the side of the oven cavity. Then, take your new seal and gently place it in position. Ensure it fits snugly along the side. As for maintenance, it's a good idea to clean the seal regularly with a mild, soapy water solution. Just wipe it down gently to keep it in good condition. When you're not sure if it's the right part for your oven, don't hesitate to contact us with your stove's model number. And always handle the seal with care to avoid stretching it too much and losing its proper shape.
