Product review (1 stars): LG refrigerator only lasts 2 years.
This is the successor to the LFX33975ST. I believe the had to change the model number because of the terrible repair history. Look around online for the issues surrounding these units. Many do not last more than 2 years. Watch to see how long your model has been around. If it does not have several years of history, beware!
 We have owned ours for 2 years, and it no longer cools. It has a Smart diagnosis feature. Though per two of their customer service personnel this never works for Iphones. I tried a Samsung Galaxy and it failed as well. They are estimating $400 to fix it. They will only charge $100 if they determine they cannot cost effectively fix this $3,400 refrigerator that was only good for 2 years.
