The LG LT800P water filter is LG part ADQ73613401, and you can change it in minutes with a twist and no tools. Order by the part number on your old filter. If that number is LT800P or either of its two LG part numbers, your refrigerator takes the LT800P. We stock the LG LT800P Refrigerator Water Filter ADQ73613401 in packs of 1, 2, 3 and 6.
Your refrigerator takes the LT800P when the old cartridge shows ADQ73613401 or ADQ73613408
A cartridge marked ADQ73613408 is also an LT800P, and you order this same cartridge for either number.
| LT800P detail | Value |
|---|---|
| LG part numbers | ADQ73613401 and ADQ73613408 |
| Flow rate | 0.5 gallons per minute |
| Water pressure | 20 to 125 psi |
| Water temperature | 33 to 100 degrees Fahrenheit |
If the old cartridge in your refrigerator is a Kenmore 9490, the LT800P is a compatible replacement for it. Take a photo of the label when you pull the old cartridge, and you can check the part number again when you reorder.
The LT800P is behind the bottom door bin or in a back left housing
LG puts the LT800P in one of two places, and the place depends on your refrigerator model. Each place has its own removal method. Open the doors and look behind the bottom door bin first, where the filter turns out of a filter head. If you find no filter there, check the far back left of the inside cabinet. On that layout the filter is in a housing and comes out the same way as the LT700P.
You change the LT800P in four stages
Stage 2 has a version for each layout, and the other stages stay the same on both.
Stage 1: Close the valve and drain the line
- Check your owner's manual first, because some models allow the change with the valve open.
- Close the water supply valve to your refrigerator.
- Press the dispenser paddle to drain the water left in the line.
- Place a towel or a cup under the filter to catch drips.
Stage 2: Take out the old filter
For a filter behind the bottom door bin, use these four steps.
- Open the refrigerator doors to reach the filter.
- Remove the bottom door bin from the door.
- Grab the bottom of the old filter.
- Turn the filter counterclockwise to remove it from the filter head.
For a filter in the back left housing, use these four steps.
- Move anything in front of the housing, including the top left shelf if it is in the way.
- Press the push button on the housing.
- Pull the old filter all the way down.
- Pull the filter gently toward you until it releases.
A little water can drain out at this point, and the towel or cup from stage 1 catches it.
Stage 3: Fit the new filter
- Take the new filter out of its packaging.
- Pull the protective cap off the new filter.
- Line up the tabs on the filter with the slots in the housing.
- Push the filter into the housing as far as it goes.
- Turn the filter clockwise until it locks in place.
- Check that the lock mark lines up with the reference line.
- Put back the door bin or the shelf you took out in stage 2.
If the filter does not turn smoothly, pull it back out. Line up the tabs with the slots again. Then push the filter straight in before you turn it.
Stage 4: Flush the filter and reset the indicator
- Open the water supply valve again slowly.
- Check around the filter and the housing for leaks.
- Dispense about 2.5 gallons of water to clear trapped air and fine particles.
- Run the dispenser for 30 seconds at a time, with a 60 second pause after each run.
- Repeat that cycle until 5 minutes have passed in total.
- Press and hold the Water Filter or Filter Reset button for 3 seconds.
The reset is complete when you hear a chime or the indicator turns off.
Air in a new filter or in the water line can change the taste of the first water or bring bubbles. The flush clears that air, and it also clears fine carbon particles that can come out of a new filter with the first water. If the taste or the bubbles go on after the flush, check that the filter is fully in and locked.
One LT800P lasts six months or 200 gallons
Whichever limit comes first sets the change date. Mark the day you fit the new filter, and count both limits from that day. The 200 gallon limit allows a little over a gallon of filtered water a day for six months. A home that uses more water than that needs the new filter before the six month mark.
Check the filter before the change date if water comes out of the dispenser slowly or the replacement indicator turns on. A home can also need an earlier change because of the quality of its water. Our guide on how often to replace a refrigerator water filter explains the gallon limit and the signs to watch.
A larger pack puts the next filter in your cupboard before the change date comes. At two changes a year, a 2 pack covers one year and a 6 pack covers three years.
The LT1000P and the LT700P are different cartridges
LG makes other common water filters for its refrigerators, and they are separate parts from the LT800P. We stock the LT1000P and the LT700P in all four pack sizes. Each one differs from the LT800P in part number and in size.
| LG cartridge | LG part number | Size | Location |
|---|---|---|---|
| LT800P | ADQ73613401 | 7 3/8 inches long by 1 5/8 inches in diameter | Behind the bottom door bin, or the back left housing on some models |
| LT1000P | ADQ74793501 | 5 3/8 inches long by 1 5/8 inches in diameter | Same two places as the LT800P |
| LT700P | ADQ36006101 | 6 7/8 inches by 1 3/4 inches | Far back left of the inside cabinet |
The LT1000P is two inches shorter than the LT800P, and that length gap is a plain sign that the two are separate cartridges. If your old cartridge shows ADQ74793501, your refrigerator takes the LG LT1000P refrigerator water filter, and our LG LT1000P guide covers that cartridge in full. If your old cartridge shows ADQ36006101, your refrigerator takes the LG LT700P refrigerator water filter.
The air filter that removes odors inside the refrigerator is a different part from the LT800P water filter.
LG lists NSF 42 and NSF 53 certification for the LT800P
NSF/ANSI Standard 42 covers aesthetic effects, and NSF/ANSI Standard 53 covers health effects. LG tells you to look for the NSF logo on the package when you buy a replacement.
Set the next LT800P to arrive every six months
With Subscribe and Save, you choose the interval once and we ship your next filter on that schedule. The new filter arrives when the old one is due, and you have one less date to track. On our LT800P page, choose a delivery every six months to match the rated life of the filter. You can also choose a delivery every three months or once a year, and you can adjust the interval, pause a shipment, skip a delivery or cancel.
Check the label on your old filter for LT800P or either of its two LG part numbers. When you find a match, order the LG LT800P Refrigerator Water Filter ADQ73613401 in the pack size you want on hand. Our LG refrigerator water filters collection lists the other LG filters we stock. Call us at 855-789-3278 if the label on your old filter is too worn to read, and we will help you find the filter your refrigerator takes.
