What people are saying

Rated 4 out of 5 by from Love the spaciousness. We have had it for years. I think we bought it in 2013? Love everything about it. The ice machine just went out about three months ago. I’ve been trying to replace it myself. It looked super simple (which it was). But they kept sending me the wrong part (6 times I was sent a 6 wire connect even though I told them I needed a 3 wire connection. They always said yes it is a 3 wire. Then I would get it and it would be a 6 wire! I finally just ended up replacing the whole unit. It was super easy when I actually got the right part. It was only four screws.

For LG LFX31925SW, ordered the ACQ85448401 Refrigerator Deli Drawer Cover after I broke the clear plastic. Unfortunately, the replacement cover does not have the builtin clips that hold the 3 clear plastic windows in place. Is that correct? Suggestions?

Asked by: ArizonaTTR

Does the bottom freezer ever defrost itself

I have ice at the back wall of bottom freezer
Asked by: Bemartz
We regret the trouble you have experienced with this refrigerator. This model is designed with a defrost heater. However, if that which has been experienced is ICE, more than FROST, then there may be something more going on, such as a water leak, or the heater not operating properly. It is recommended to thaw the refrigerator and freezer, clean up any water, and then reconnect it. Allow it to cool for a few hours before loading it with food. If this unit starts having this problem again, 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

I have the Er and 1F symbols on the refrigerator control panel. How do I fix this problem?

Asked by: ronbrown1
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

To prevent the door from hiting a wall when opening. Can you limit the door to only open to 90 degrees?

Asked by: Ohiohomeowner
We regret the trouble you have experienced with this refrigerator. While it may be possible to slow the opening of the door by raising the front leveling feet, nothing will fully restrain the opening of the door like manually controlling it.

which lg refrigerators come in white with 2 icemakers. the one that came up first when I searched for this did not list 2 ice makers???

the model that came up when I searched for 2 ice makers was the 30 cubic foot plus size with 3 drawers in the freezer (exactly what I want... ) but it did not list 2 icemakers???
Asked by: penelope
There is only one ice maker, the one in the door. The freezer has a large ice cube bin so that you can store up a large amount of ice for an occasion. All you do is open the double door and remove the ice cube maker bin, empty it into the large bin in the freezer, then return it to the ice maker in the door and make another batch.
