Using this Westinghouse Chef grill left - hand door hinge is straightforward. First, make sure your oven is turned off and cooled down. Remove the old hinge carefully. Then, align the new hinge in place and use the appropriate tools to secure it. When handling the hinge, be gentle to avoid bending it. In terms of maintenance, keep the hinge clean by wiping it regularly with a soft cloth. If you notice any signs of wear or if the door starts to close unevenly, check the hinge.
