Using this Westinghouse oven door seal is easy. First, make sure your oven is turned off and cooled down. Then, carefully remove the old seal from around the oven door. Next, place the new seal in position, starting from one corner and working your way around the oven. Make sure the small metal hooks fit properly. Remember, always double - check your stove's model number before buying to ensure a proper fit. For maintenance, clean the seal regularly with a soft, damp cloth. Avoid using harsh chemicals as they can damage the seal. If you notice any signs of wear or damage, it's a good idea to replace the seal to keep your oven working efficiently.
