Removed old air diffuser and installed a new air diffuser. Very easy to replace, requires a 1/4" socket with a socket extension to remove one single screw at the front of the air diffuser. Once the screw is removed the cover can be removed by tilting the top edge down and then pulling gently forward. Be careful when pulling forward my old air diffuser wires were caught a little on the cover. Next, disconnect the electrical connections by pulling them apart. There is a tab that needed to be lifted a little on the connector to unlock the refrigerator connector. Then pull the old air diffuser out of the side of the inside wall. Install the new air diffuser back into the same place the old air diffuser came out, connect the wires using the connectors, and replace the cover.
