So if your LG LT1000P is telling you that now is the time for a water filter change, we’re here to help you do this easy maintenance task at home. Follow the simple instructions to quickly replace your LG water filter and run cool clear water again soon. LG French Door Water Filter Part Number: ADQ36006101 

Step 1: Remove or Lower the Top Shelf

Your water filter can be found in the top left back corner inside the fridge. It looks like a white oval-shaped object on the ceiling of your fridge. This is the filter housing. Remove anything from your fridge that might stop that housing from swinging down fully. Remove anything on the top shelf and, if the top shelf is set high, remove or lower the shelf itself.

Step 2: Open the Water Filter Cover

On the side of the filter is a small button that says “Push”. Push it while pulling that end of the housing down. It will open like a shell, swinging down from the back hinge. This will reveal the water filter.

Step 3: Pull the Water Filter Downward to Release

The water filter is a bottle-shaped object with the neck stuck into the back of the filter housing. It will not come out immediately. Grasp the end and rotate it down in the same direction as the housing.  When it is all the way down, pull toward you to release the filter. Throw the old filter away.

Step 4: Unwrap the New Water Filter Fully

When you unwrap the replacement filter, make sure you remove all of the packagings. Including the protective cover on the rubber o-rings. This is necessary for the filter to create a watertight seal.

Step 5: Line Up the New Water Filter Tabs with the Housing

You will notice that the new water filter has wing-like tabs on the cap. Align these with the slots in the water filter housing in the same position as you removed the previous filter. This is key to the new filter fitting into place.

Step 6: Press Then Rotate the Water Filter Into Place

Press the new filter tabs and cap into the slot. When it feels firm, rotate the filter back up into the housing. It should fit snugly.

Step 7: Close the Cover Firmly

Rotate the water filter housing cover back into place. Press firmly until you hear the click of the button latch closing to hold the housing shut. You have just successfully replaced your LG french door fridge water filter. But we’re not quite done yet.

Step 8: Run 2.5 Gallons of Water Through the Filter

The final step is to run about two and a half gallons of water through the filter in order to clear your system of any air bubbles, contaminates, and loose charcoal. If you skip this step, you may be seeing a little odd debris or black flecks in your ice and drinking water.

Do not pour 2.5 gallons of water through the water dispenser all at once. This can overload the system, as your fridge is not prepared to work as a sink. Press the water button for no longer than 30 seconds at a time. It is recommended to give the filter 60 seconds between dispenses to cool down. That means 30 on and 60 off until you have run 2.5 gallons through the system.—Congratulations. You have not completed the replacement of your LG LT1000P french door refrigerator water filter.
