Product review (2 stars): WARNING: Some suppliers provide non-OEM parts
Do not buy from Ice-Machine-Supply.  Original pump lasted over 10 years, while the replacement looked OEM only lasted 10 *months*.  I have ordered a replacement from a different supplier.  Looks like I should have just paid LG for a true OEM part the first time.

Update:  Ordered a replacement in Feb 2017 and that failed in Oct 2017.  The replacement looked legit (LG branding on the box).  It must be a knockoff.  There is no way that a replacement pump lasts 6 months while the original lasts 10 years
