What People Are Saying

Rated 4 out of 5 by from Door in a door. Great feature The door in a door is best feature you can put on a refrigerator. The unit has a open door alarm which could be a lot louder or have a volume control. Over all this one of the best refrigerators I've owned. I would buy again.

Rated 3 out of 5 by from Poor Cosmetic quality I bought this product Nov, 2013 and two years later the doors are developing rust spots without any applied scratches, etc. to the surface.

Rated 4 out of 5 by from Cool Features The door in a door is the best option of any refrigerator I've had. Being able to get milk or coke out without opening the the big doors keeps from letting the cold air out. The dual ice maker is a big help in the summer time. Over all the one of best consumer refrigerators I've seen.

Rated 5 out of 5 by from I absolutely LOVE this refrigerator!!! This is my favorite appliance in our newly remodeled condo. The kitchen was planned around this fridge because I fell in love with it the minute I saw it at the store. Our contractor messed up and I cannot fully open the left door, but we can manage. The split door is a great feature! The serving tray compartment is also very useful. The freezer drawer opens easily. No need to pull it hard and hurt your back in the process. The L.E.D. lighting is bright and awesome. This fridge is perfect!!!! I highly recommend it!

Rated 5 out of 5 by from This Fridge is huge There is so much room. The Lighting, sliding drawers, and adjustable shelves. Great on electric bill also, Had this unit for one month and my electric went down $6.00 dollars. I know this because my other Fridge use to run approx. every 15 minutes. I know this unit is going to save on energy usage. Thanks LG, Great Product :) Very Happy consumer thus far.

Rated 5 out of 5 by from Just what we needed! Outstanding third door! We needed an upgrade from a very old two door fridge! One day we decided we had enough and went shopping. Found this as replacement because of size (29 CF), but the real seller was the third door in the door that give a quick opening for the multi-use items we use most often, like creamer, milk, soft drinks. The wife uses it also to store sauces and condiments she may use in cooking. We have had it for about a month now and enjoy the filtered water and the bigger lower freezer. It is quit, and makes a nice addition in the kitchen. Thanks to LG for creating a French Door like this!

Changing the temperature

I can see how to change the temp, but it only goes to colder. I need to move it back up.
Asked by: JGran
Hello JGran, thank you for your inquiry, we're regret to read that moving the temperature up in your LG Ultra-Large Capacity Door-in-Door™ 3 Door French Door Refrigerator with Dual Ice Makers, Model # LFX29945ST is proving to be a challenge. Just to clarify, when you say "it only goes colder. I need to move it back up." what exactly happens when you set the temperature to a higher temperature setting? When you make changes, it takes 24 hours for the temperature to stabilize so you may need to give the refrigerator more time to adjust the temperature. You also will need to make sure that none of the vents in the interior of the refrigerator are blocked. Move any food or anything that may be blocking the vents to another section, but again, give it 24 hours...^IFV

The sensor does not work to keep freezer air out of refrigerator. It stays closed.

I unplugged it, but I think I need a new one. Where can I find one or what is wrong with the sensor?
Asked by: Lyles
Lyles, I'm having the same issue. Too much cold air entering the refrig and freezing food. I've had the whole inside back panel with the damper/sensors replaced and the control board and the issue still exist.

After following all of the trouble shooting tips in the manual, the ice still tastes of chemicals. How can I fix this?

We've had the fridge for 2 months and in the last 2 weeks the ice has started tasting funny. I've replaced the air and water filters. Cleaned the makers and bins as well as the fridge itself. The water out of the regular tap tastes fine.
Asked by: areams
We regret the trouble you have experienced with this refrigerator. If the regular water line tastes fine, then this refrigerator 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

Does this model dispense crushed and cubed ice?

Asked by: TerryKath
Answered by: Martin44
Date published: 2014-10-06

Why does the cubed ice light stay on when all the other panel lights go off?

All control panel lights go off normally after a time delay except the glass with cubed ice.
Asked by: robare
We appreciate your interest in this television. When the ENERGY SAVER mode is active , only the ICE MODE lights will remain active. The description provided is normal operation.
