Noisy LG Refrigerator Repair

Our 2 year-old LG refrigerator (model LFXS24663S) was making a noticeably loud "buzzing" sound while the compressor was running. The sound measured around 72dB from about 10ft. I contacted LG support and they were not helpful at all. There are other videos on UA-cam documenting this sound ( • Lg lfcs25663s vibratio... ). I did a little troubleshooting and determined the source of the sound was a resonance condition with the plastic condenser drip pan and condenser fan shroud. After a bit of trial and error I was able to correct the condition. Three things needed to be done to eliminate the noise; 1) correct the manufacturing defect with the condenser fan shroud 2) isolate bottom of the drip pan from the refrigerator base frame with foam 3) isolate the back of the drip pan from the refrigerator lower-rear skin.
I do not show how to remove the lower, rear access panel from the refrigerator. There are several videos that demonstrate how to do this if you need guidance ( • LG Refrigerator Disass... ). Simply remove the six Phillips-head screws securing the panel and remove.
This is a rather easy repair to make requiring only basic hand-tools and a small amount of packing foam sheeting. If you can remove and install a screw, you can make this repair.
The noisy condition is attributable to poor manufacturing quality control and poor design quality. This was my first experience with LG product support and I found it to be poor. As a result I could not endorse LG products.
