How to Replace your Water Filter

Here's all you need to know to change your refrigerator water filter. We're happy to show you how, step by step.



Keeping your refrigerator in tip top shape with a brand new water filter is a smart move. By changing your LT800P / LT800PC water filter on a regular basis, you'll continue to reduce contaminates such as iron, particulates and chlorine in your drinking water and ice cubes. You'll notice the difference!

The sale of counterfeit and deceptively labeled water filters is a growing problem in the U.S.. 3rd party filters are not guaranteed to properly filter water in your LG refrigerator and may cause damage not covered under the terms of LG's warranty. Always use new LG filters with your LG refrigerator. It is essential that the manufacturer's recommended installation, maintenance and filter replacement requirements be carried out for the product to perform as advertised.

The LG LT800P / LT800PC Replacement Refrigerator Water Filter (part# ADQ73613401) is compatible with the following LG refrigerators¹

Rated 2 out of 5 by from I wish I would have returned it. We have had this refrigerator for about a year now. I am irritated with myself for not immediately returning it and getting something different. While the storage is adequate, there is no meat drawer inside the refrigerator. I had to purchase additional storage compartments to hold cheese and lunch meat. In addition to that inconvenience, the refrigerator is loud. I mean loud! When it is running a cooling cycle it hums so loud I can hear it in the upstairs part of the house. Forget about sleep overs or napping on the couch near the kitchen. In just under a year of owning this refrigerator our ice maker quit working. The only thing positive I can say about that is that LG was great about getting the ice maker replaced for us. The process to request a repair was easy and turn around time for repair was pretty quick. Don’t be fooled by the fancy door. Skip this fridge and get something else.

Rated 5 out of 5 by from Very Good Service I have it for 2 years and have not had an issue with it. It has been working nicely since then. Provides signal display for water filter change. My only issue is with the water dispenser; the water flow could be is too slow. There’s also a slight misalignment at the top of the doors; the freezer door is a bit higher than the other door.

Rated 1 out of 5 by from It works Seems to take taste out of water. Ice cubes come out perfect when ice maker is working. I like the idea that it removes Chlorine taste and odor, Lead and Mercury as well as other contaminants.

Rated 4 out of 5 by from Good filter I automatically replace my cartridge filter every six months to keep my water great tasting. This filter does an adequate job. It is tricky to get in place though. You need to align it so that you have no drips from water area. Usually after three tries, it works like a charm.

Rated 4 out of 5 by from Very Good Refrigerator We are very happy with our new LG 4 door refrigerator. Here are the pros and cons. Pros: -Lots of Room and flexibility for storing items. -Very well lit. Great visibility. -Great Ice Maker and Dispenser. Great crushed ice. -Love the Black Stainless Smear-Resistant Finish. -Love the drawer system in the freezer. -The extra convenience door on the right side comes in very handy for storing often-used iterms. -After 7 months this Refrigerator works perfectly. Very accurately keeps the temperature at the given settings. Additionally, we signed up for replacement water filter delivery from LG every 6 months. Very convenient. Cons: -Design Flaws: -The doors do not have an “Easy Close” feature! This is especially problematic with the upper left door which houses the ice maker and is heavy. If you don’t take the care to ease the door shut it will slam hard and items inside can shake loose or break. This problem is exacerbated by the absence of outside handles to hold on to while you close the door. -The upper left door has a retractable strike plate that the right door engages when you close it. When the right door is opened and the left door remains closed the strike plate prohibits the right crisper drawer from opening more than half way. While the left crisper drawer is accessible by opening only the left door, both doors must be opened to access the right crisper drawer. This problem could have been remedied by simply making the crisper drawer an inch or so more narrow. Poor Design!! Feautures I would like to have seen: -Auto Fill on the Water Dispenser. A refrigerator of this caliber should have an auto fill, pre measure and auto stop feature on the Dispenser. -It would be nice to be able to convert one of the freezer compartments to standard refrigeration to expand the refrigerator capacity. I’ve seen this feature on several models available this year. All in All we are happy with our new Refrigerator. Hopefully LG will address some of the issues that I listed in future models.
