Then, align the new hinge with the mounting holes on your oven and screw it in place. Make sure it's firmly attached so the door will open and close smoothly. As for maintenance, keep the hinge clean. You can use a mild cleaner and a soft cloth to wipe away any dirt or grease. Check the hinge regularly for signs of wear. If you notice any issues like the door not closing properly again, don't hesitate to contact us. And remember, if you're ever unsure about whether this hinge is the right fit for your oven, always reach out with your model number.
