What people are saying

Rated 5 out of 5 by from Excellent consumer service I had a problem with my LG refrigerator compressor. I did call the consumer service and explained my problem. they asked for my serial number and discovered that my 10 year warranty was still valid. I did receive the compressor and parts needed to replace the old one. Now I have a new refrigerator at my home.

Rated 3 out of 5 by from This is a very large refrigerator I had my fridge for 9 years until the compressor died. I contacted LG and they said that their technician could fix it. I had to pay $125 for the service then about $250 in labor. ( not free) and it is under warranty still. I called and LG said a tech the compressor was on back order. So they don't know when it may be fixed. I was told this happens a lot.

Rated 5 out of 5 by from Nice Fridge I bought this over 7 years ago and it’s been great. The compressor went out recently but it was warranted. Hopefully it works as well as it did.

Produce drawer seems to be freezing up, causing all the food into to freeze.  Any help with what to do? 

Asked by: Lisaboymom
When the refrigerator temperature in the LG 31 cu. ft. Super Capacity 3-Door French Door Refrigerator w/Door-in-Door®, Model # LFX3194ST is set too low cold air often settles at the bottom of the fridge. This results in the crisper drawer freezing food before other items are affected. Generally, a refrigerator's temperature should be between 37-42°F to avoid freezing but still keep food cool. Check the settings for the crisper drawers. You can control the amount of humidity in the moisture-sealed crispers by adjusting the control to any setting between HIGH and LOW. Freezing is more likely to occur when the refrigerator does not have enough food to absorb the cold air...^Ivan

Hi. I need to replace LFX31945ST refrigerator door gasket for both side. Where can I order them? Thanks.

Asked by: Rck327
There should be a nameplate attached to the inner right wall in the refrigerator compartment of your LG 31 cu. ft. Super Capacity 3-Door French Door Refrigerator w/Door-in-Door®, Model # LFX31945ST that has the serial number and model number for the refrigerator stamped on it. There is a factory suffix on the end of the model # LFX31945ST.XXXXXXX. To order the door gasket for the refrigerator, you will need that factory suffix to make sure that you get the right door gasket for your refrigerator and you can order it from our Authorized Parts Distributor Affiliate, Encompass Parts (800) 432-8542, https://encompass.com...^IFV

The freezer temperature is reading -16C on the display. However, the lower compartment of the freezer is not keeping items frozen. How do I troubleshoot the problem? The unit is only 4 years old.

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
