To determine if the oven door seal is leaking, you can visually inspect the seal for any visible damage or wear. Additionally, you can perform a simple test by placing a piece of paper along the edge of the oven door while it is closed. If the paper can be easily pulled out without resistance, it may indicate that the seal is not creating a tight enough seal. Another sign of a leaking seal is if you notice heat escaping from the oven door during use. If any of these signs are present, it is likely that the oven door seal is leaking and may need to be replaced. **
