What people are saying

Rated 1 out of 5 by from IS NOT GOOD JUNK ONLY USE FOR 4 YEAR .THE ICE MAKER IS GARBAGE .MAKING NOISE AT MEDAL OF NIGHT JUNK
Date published: 2020-07-25
Rated 2 out of 5 by from 1.5 stars isn't an option? So this one was manufactured Dec 2012, so over 7 years now. We've had multiple people come out to diagnose it, but it's always either a guessing game or we're told it's a piece and get rid of it. I like the size of it, and the look, which is why 2 stars and not one.

Rated 1 out of 5 by from Worst customer services. Bought this in 2015. the refrigerator quit working. Hire a local technitial, he told us that the compressor is broken. Trying to contact LG for customer service. Wait for about 1 hour finally spoke with someone with broken English. Was put on hold for another 1 hour without any further assistance and the call just went to silence. We already fixed some problems a couple of years ago. A piece of junk. Don't expect it last for more than 5 years.

What does er 1f mean 

Asked by: Jonnyboy2018
Hello, the IF error code indicates that the refrigerator has detected a problem with the refrigerator's ice maker fan. This can sometimes occur when frost or ice buildup occurs around the ice maker fan. This will require service, to set that up you can call in to 1-800-243-0000 or go to: https://www.lg.com/us/support/repair-service/find-repair-provider ^AC

Ice will not dispense from the ice tray and water is not filling up the entire tray only filling the trays closest to door opening. Makes a horrible clicking sound when the tray rotates to empty tray

What temperature is freezer suppose to be set at

Asked by: Mglugo
The default temperature settings for this unit would be 37 for the fresh food section and 0 for the freezer. If you wish to have an increase in ice production the optimal freezer setting for maximum ice production would be -4. The temperature in the refrigerator/freezer will fluctuate when the doors are opened and closed. Once the unit recognizes the temperature has increased beyond the desired setting, the compressor and fans will turn on to lower the temperature back to the desired settings.
