What People Are Saying

Rated 1 out of 5 by from Horrible! I've had nothing but problems with this refrigerator. The motor has been replaced and it continually stops making ice, giving an ER code on the front panel. It also randomly thaws out. It is a beautiful refrigerator, very spacious

Rated 1 out of 5 by from Not satisfied Purchased this refrigerator 13 months ago from Home Depot, in the 13th month it it was 45 degrees in the refrigerator and 24 in the freezer (not cold enough). Called H D repair man came out said it needed a mother board 1 week later installed mother board still not working installed another board and 2 sensors, still not working, they installed a new compressor, still not working, next week they are going to install another sensor. This has been going on for 2 months, just getting the runaround. Will never buy LG again.

Rated 4 out of 5 by from Good but not great! Fails in Quality. I've had my fridge for just over a year now and love the size and layout. What I don't like is the quality of the interior components. Everything is very "plasticy". The ice-maker easily jams, the roller shelf in the freezer easily comes off it's tracks, and the shelves in the refrigerator bend/bow with just one 1/2 gal of milk. Luckily it is BIG so stuff can usually be spread out to relieve the shelves of too much weight. This unit is also quite a bit deeper than normal and my personal preference would have been to make it taller not deeper - just to save floor space. That said, I do still like it but I just wish the quality was better. My old fridge was 27 years old and I doubt this unit will last 1/2 that long - but I guess that is the world we live in now.

Rated 3 out of 5 by from Repair already? We are disappointed that after 11months the fan needs servicing. What's up with that. This unit does so much, but a fan should not fail so soon.

Rated 5 out of 5 by from Love it! We have the refrigerator for about 2 months now. It's very quiet. Tons of space for everything - including big pizza boxes... We thought that the little shelf by the ice maker box will be a waist... turns out that salad dressings, BBQ sauce etc' fit just right and are in a perfect place for a quick reach...

Rated 5 out of 5 by from Excellent refrigerator We are pleased with all the features of this refrigerator. The storage features - the drawers, etc - are very convenient and the large storage size is very helpful. It offers a pleasing look in our new home, and we would certainly purchase an LG again.

Rated 5 out of 5 by from Best refrigerator I have ever owned Before I purchased this model I owned a 27 cubic foot LG French door refrigerator. It was good, but this model is substantially better. I am particularly impressed by the changes made in the ice maker. The 27 cu. ft. model had crescent shaped cubes that tended to get caught in the chute. This model has smaller, more uniform cubes that don't jam the chute. The freezer is outstanding. Because of the drawers within the freezer, it is very easy to locate whatever you want to find. The only change in this model that does not seem to be an improvement over the 27 cu. ft. model is the water filter. The addition of a drop down door for the filter seems unnecessary and prone to breakage. The air filter is also somewhat of a joke. A box of baking soda works better. One feature of the 27 cu. ft. model that might be better than the 32 cu.ft. model is the display. I liked knowing how many months of filter use were left, and also liked the fact that the display was on all of the time not just when the user opened the door. Despite these little nags, the refrigerator is outstanding, and LG will continue to be my appliance of choice.

Should the ice be melting into clumps and stopping up the dispenser all of the time??

My ice ALWAYS melts into clumps and then stops up the ice dispenser so it doesn't dispense. We have to take out the ice bin and clear the clump of ice. This happens every couple of days. We also have tried to set the temperature of the freezer and fridge very low but this has not helped either.
Asked by: Thicks
Mine did this after owning it for 10 months. LG replaced the ice maker under manufacturer's warranty. The problem will not get better until you have the ice maker replaced.

How do I change the fresh air filter? on my model # LFX33975ST LG refrigerator

Asked by: Patsipoo
The square at the upper left in the back of the fridge when you open the door, is twisted to the left and removed. Replace with the new one and twist it to the right to fasten it. How easy is that?

My water has slightly high salt content, is there a water filter for this appliance that will remove salt from the water?

what is message er on fridge and if on freezer

Asked by: mawmaw
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

Does the LFX33975ST have an ice maker in the freezer or is it shared with the ice maker in the door?

Asked by: dbhb
It only has one ice maker. You have the option to increase ice production and it works well.
