What People Are Saying

Rated 2 out of 5 by from Mediocre refridgerator I've been very happy with my LG washer and dryer that is now 10 years old. The refrigerator is good but the ice maker is possibly the most frustrating part of any appliance I ever had. Constantly jamming and I have to stick my finger up into the dispenser to open the door so the ice falls out. Not sure I would ever buy another LG refrigerator.

Rated 5 out of 5 by from Very Happy This refrigerator is perfect for our needs. Runs quiet, cleans easy, temp changes easy. Only critique would be pull out freezer drawers could be rack style instead of plastic.

Rated 4 out of 5 by from Very good features Excellent product. It's one of the best refrigerator that I ever had. Very spacious inside and easy to keep clean. The only thing that I'm concerned is about the drawer in the freezer that gets stuck sometimes when I open the door.

Rated 5 out of 5 by from love this fridge Bought it to replace a replace the spare fridge that didn't survive a move while redoing the basement. Moved the kitchen fridge which was 20yrs old to the basement and bought a new main fridge. Love the size, fridge and freezer, and the crushed ice. Another shelf on the door would be nice, but not a show stopper.

Door left open, fan making a noise, so we we moved everything. Turned the power off. Went to work, come home cleaned it out. Turned it back on, still around 50 degrees?

Asked by: WDP789710
We regret the trouble you have experienced with this refrigerator. When a refrigerator is at room temperature, it can sometimes take 24 hours to regain the proper cooling temperature. If the temperature has not been reached after this time, then the unit 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

The linear compressor says "Er 1F" and none of the buttons are clickable. What is the problem and how do I solve it?

Asked by: Tcompress
A "F1" or "1F" error code on the LG Ultra-Large Capacity 3 Door French Door Refrigerator with Smart Cooling, Model # LFX25974ST indicates a problem with the ice blower fan or the ice maker motor. For that error code, unfortunately there is no troubleshooting that can be performed. The refrigerator will require a repair service.

What temperature should refrigerator be set on? And freezer

Asked by: Deuce1910
The default temperature settings for the refrigerator compartment and freezer compartment for the LG Ultra-Large Capacity 3 Door French Door Refrigerator with Smart Cooling, Model # LFX25974ST are 37°F and 0°F. The amount of food you have stored in the refrigerator and other factors will determine what your temperature settings should be. The more food that is in the unit, the hotter the ambient temperature of the room or the more the unit is opened and closed, the colder the refrigerator has to be set because it will take more for the unit to keep cool...^IFV
