I suspected a circulation issue as the compressor seemed to be cooling. A call to LG for a diagnostic check confirmed a fan issue. I researched on the website but called a tech to order to make sure I get the right part. The tech was knowledgeable and very helpful. It arrived the next day and I installed it yesterday. The video showed the steps and it took about 45 minutes to complete. The hardest part was disconnecting the 4 electrical connectors to remove the panel. I didn't need to remove the railing as shown as my panel must be a bit smaller. Today everything seems to be working fine so I filled the refrigerator and freezer with confidence in my repair.
