Product review (1 stars): Ice maker will likely die.
This is a review for the slim ice maker found in this and other LG refrigerators.  I have an LFX31925ST, but the ice maker is the same for this model (see LG's troubleshooting page for their 3 types of ice makers). They call this a twist / flex tray with IR sensor aka the Super Slim Plus Ice Maker.  This ice maker has failed 4 times in 5 years.  The first time was under warranty and I had no troubles getting it replaced.  The second time the fan, ice maker, and 1/2 of the parts for the freezer were replaced.  This was a service recall which would only be replaced if you called in about ice maker troubles.  The third time was two years ago, and they provided a "one time courtesy repair" after I mentioned something about the class action lawsuit.  It has failed once again, and LG will do nothing to help me.

Everything else about the fridge is great.  I had read the reviews about the ice maker and fan problems, but I thought I'd roll the dice on the scratch-n-dent. I'm a sucker for scratch-n-dent, and in this case, sucker was right.
