My noise crunch/grind sound…3 years Old! There are several You-tubes on this..All point to a bad motor drive! LG should replace the part if it truly backs up its 10 year Warranty.
I have the exact same model # and noise. LG OEM parts says ABT7298920(6), and double the price as ABT7298920(2). Wondering if you came across this as well, any differences? Much appreciated!
I noticed that as well and research led me to think it's the exact same part but a later production run? In the end I went with this one as it was cheaper, I think, and it worked.
