What people are saying
Rated 3 out of 5 by from Door doesn't stay shut! I bought this frig in 2013. About 3 yrs into it the right door will not stay shut. It feels like there is a magnet that isn't catching but 3 services calls later no knows why. One service guy said my house was sliding. He didn't know what to say when I said "And the other door?..." One tech wanted to charge us 450.00 to replace the seal but I know better and got a new one myself. It didn't fix it. We still are having to shut the left door very carefully so there is no air rush that opens the left door. Hate this problem but it has a great alarm!

Why is my refrigerator not making ice?

Asked by: Owner15
We regret the trouble you have experienced with this refrigerator. Typically, the lack of ice production will be related to the internal temperature of the freezer/ice compartment. This occurs most frequently near the original installation of the product, as the machine works to reach a proper cooling temperature, or if there is high traffic with doors being frequently opened and closed, causing a rise in the temperature. If this is not the case, please contact our Customer Interactive Center at 800-243-0000 to further troubleshoot this matter.

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
