Rated 5 out of 5 by from LG makes the best refrigerators! This is my second LG refrigerator and both have exceeded my expectations. Lot's of space, easy to see everything, runs quietly and has terrific features like in door ice and water. The new door within a door is great as well for frequently accessed foods or if you have a "looker" that leaves the door open for long periods of time. Go LG refrigerators!

Rated 1 out of 5 by from Poor Exeperience We bought this refrigerator as showpiece of our kitchen...what a mistake. We have had 5 failures of the refrigerator since purchase. It keeps freezing up and have lost hundreds of dollars in food not to mention the lost time to be here for service technician. The fans, defrost heater, control panel has been replaced. Some parts TWICE! Every other LQ appliance we own is great, but NOT THIS!!!!!

Rated 4 out of 5 by from Like the size Exactly one year, and after the warranty, we started having problems with the ice maker. We were able to reset it a couple times and got it to work. Also the front panel, where the ice maker/water filter is started to come off. It is half on. It is a hard plastic. Not sure how that could be fixed but it sure makes the fridge look ugly and older then it is. Other then that it keeps things cold and I really like the size of it.

Rated 1 out of 5 by from Can't clean up spilled kool-aid! I loved this refrigerator right up until my kids spilled red kool-aid and some seeped under the drawer hood cover. Now I have to look at the spill every day and can't get to it to clean it.

Er in the refrigerator led and If in the freezer led on the left front door. What's up?

Asked by: LG Jeff
The ER IF code is indicative of a problem with the Icemaker Fan or its motor. This can potentially be resolved by allowing the refrigerator to thaw for about 4 hours, and then reconnecting it. If it does not, then the unit will likely require service. To make service arrangements, you may either contact our Customer Interactive Center at 800-243-0000, or you can check our Repair Provider Lookup on our website, at http://www.lg.com/us/support/repair/support-repair-provider-lookup.jsp.

What should the freezer setting be used

Asked by: JDKC1219
It is recommended that, when the unit is first installed, the freezer temperature should be set to 0 degrees Fahrenheit, while the refrigerator should be set to 37 degrees. Once the unit reaches these temperatures, you may change the setting to however you would prefer.

Bought this about a month ago. All the sudden the fridge will not stop beeping. I am not sure why but the doors are all shut and everything is cold. any help would be great.

Asked by: xman2yman
We regret the inconvenience you have experienced. Generally, the only beep in this system would be related to the doors being open to some extent. If this is not the case, then the refrigerator may require service. To make service arrangements, you may either contact our Customer Interactive Center at 800-243-0000, or you can check our Repair Provider Lookup on our website, at http://www.lg.com/us/support/repair/support-repair-provider-lookup.jsp.

I'm getting a white substance at the bottom of a glass when I use the ice maker, both crushed and cubed. I emptied the tray and washed it out. It did not help. Water alone is crystal clear. How do I get rid of it?

Asked by: Homeowner78
We regret the trouble you have experienced with this refrigerator. If there is some form of sediment in the water, then it is recommended to check the water filter, to see if it needs to be replaced. Otherwise, please contact our Customer Interactive Center at 800-243-0000.
