Using this Westinghouse door hinge base is easy. First, make sure your fridge is unplugged for safety. Then, locate the old hinge base on the right - hand side under the fridge compartment door and remove it. Install the new hinge base in its place, making sure it's firmly attached. As for maintenance, you can wipe it down with a damp cloth every few months to keep it clean. If you notice any looseness or strange noises, check the attachment and adjust it if needed. Before purchasing, always double - check your fridge model and PNC number against the listed compatible models. If it's not listed, contact us to confirm fitment.
