Quick maintenance. Years of reliability

In life we learn early that it's better to be safe than sorry. And with your refrigerator it shouldn't be different. Even though your refrigerator is so reliable it comes with a 10-year warranty on the linear compressor, taking a few minutes from time to time to check on basic functions will keep your investment running even longer.

Changing your LG REFRIGERATOR's Water Filter

Learn how to change the filter of your refrigerator and you'll be able to always keep water and ice tasting great. Below you will find tips to know when the time has come, and step-by-step instructions so you can do it easily.

How to Change
Your Water Filter

Choose a section below or simply click
on "next" to begin.

  • Your filter performance will depend on how much you use it and on the water source quality, but a good rule of thumb is that it should be changed sometime between 3 and 6 months, at the most, or as specified by the manufacturer.
  • When you reset the filter indicator on your control panel, it will start counting 6 months from the day you changed your filter. Always change your filter when the indicator reaches 0.
  • If ice and water do not taste good, you may want to change your filter earlier.
  • Keep an eye on the water flow. Lower water flow may indicate that your filter is becoming clogged with particles and it's time to change.
  • With time you'll learn what best works for you. If your water and ice consumption is large, you may want to change your filter every 3 months.

Your water filter will only improve the quality of drinkable water.

When water sits inside the water reservoir for too long, it may gain a weird taste. Dispose of the first few glasses and try again.

Well water is more likely to contain contaminants than treated water and may need more frequent filter changes.

After 6 months, unabsorbed water contaminants and newly formed bacteria can saturate the filter, and could cause contaminants to leak back into the water. If that happens, the water may contain contaminants that the filter is unable to remove.

Not changing the filter could reduce the water pressure and make it ineffective. So keep an eye out for lower water flow.


The time has come to change your water filter. Follow
these steps and you'll do it in no time.


If you don't know where the filter is, let's locate it first. It should be visible behind the light cover, on the top shelf.


Prepping for the job is important. So first, remove the top shelf to give you more space to move around.


Time to remove the light cover. Press
the release clip on the bottom of the
cover and pull it out and up.


If your refrigerator is brand new, there's a plug you'll have to
remove before installing the filter. Just twist that plug all the
way to the left and pull it down. If your refrigerator is not
new, go ahead and jump to the next step.


Now take your filter and remove the red cap. Check the two black O-rings and make sure they are not damaged in any way. This will help avoid any leaking.


At the bottom of the filter, you'll see a lock and unlock indicator. Turn the filter to the right to lock it, and to the left to unlock it.


Line up the unlock indicator on the filter
with the arrow on the unit and then push
the filter up into the filter port. Keep
pushing it up and turn the filter to the right
to lock it in place. The arrow on the unit
should line up with the lock indicator.


Replace the light cover and the shelf.


You're almost done. Just press and hold a cup in the dispenser until water starts dispensing. Be patient. It could take up to 5 minutes. Once water starts flowing, dispose of the first 2 gallons to flush out the lines.

STEP 10.

And last, but not least, open the refrigerator to
check for leaks from the filter in the freezer.

Changing Your LG
Refrigerator's Air Filter

It’s best to change your air filter approximately every six months and/or when your CHANGE FILTER light comes on your LED control panel. Follow these step-by-step instructions on how to change your air filter.


STEP 1 - Locate your air filter

Let’s start by first locating your Fresh Air Filter. You’ll find it centered at the back of your refrigerator just above the top shelf.

STEP 2 – Remove your old air filter

Twist your air filter cover to the left to detach it from the refrigerator wall. The filter is located on the inside of the filter cover. Remove and discard the old filter.

Back | Next

STEP 3 – Install a new air filter

Place a new filter inside of the cover with the side that says “Front” facing outward. Then place your air filter back in your refrigerator. Twist the filter cover to the right to re-attach it to your refrigerator’s wall.

Back | Next

STEP 4– Reset your air filter sensor

After changing your air filter, push and hold the Air Filter button for three seconds to reset the filter sensor.



It’s important to change your air filter periodically to help eliminate any fridge odor.


Even if it's been a while, cleaning your LG refrigerator is fairly easy. You'll need some gloves, detergent, baking soda, vinegar, and clean, warm water. Ready to start? Let's go.

  • Before you begin to clean your refrigerator, turn the temperature
    control to "off" so you won't overwork the linear compressor, which
    is the refrigerator motor.
  • Remove everything from your fridge so you can identify anything
    that has spoiled or expired. If you don't know for how long
    something has been in there, you'd be better off throwing it out too.
  • Use a cooler to keep everything you're not throwing out cool while
    you clean. It's ok if you don't have a cooler large enough. Improvise
    by using a large cardboard box with a towel on the bottom and another on top.
  • Remove shelves, baskets and racks. Put them all to soak (maybe
    in your bathtub?) while you clean the rest of the fridge.
  • Wipe down the entire inside of the refrigerator using a dishcloth
    and a mild solution of warm water and detergent. Remember to
    clean the door shelves, the rubber seal around the door and
    where the door seal touches the refrigerator.
  • Use vinegar with a clean cloth for tough stains. Rub in a circular
    motion. Prefer vinegar to bleach or other chemicals because it's
    a natural, safe cleaner.
  • Mix about ¼ cup of baking soda with a half-gallon of warm water
    and use it to wipe down the inside of the refrigerator and then
    rinse and wipe dry. This will help eliminate odors.
  • Remember those shelves and baskets you put to soak? Let's go
    back to them. Rinse them thoroughly, wipe them dry and put
    them all back in the refrigerator, just like you found them.
  • Put all that food back where it belongs, but not before wiping off
    glass jars and plastic containers with warm water and a dishcloth.
  • Turn your refrigerator temperature control back to the
    recommended setting and let's clean the exterior.
  • If you have a painted or plastic exterior refrigerator, use a
    solution of warm water, detergent and a sponge to clean it. Then
    use a damp cloth to rinse and a soft cloth to dry it. If you have
    stainless steel or any other type of metal exterior, use a mineral
    oil based stainless steel cleaner.


Every now and then, it's a good idea to check on a few things to make sure your freezer keeps working just as it should. Frost may build up, water lines can get bumped and even simple things like the ice bin overflowing could turn into more serious issues if they go unchecked for too long.

Caring for Your
LG Refrigerator Freezer

See what to keep an eye for and make
your routine maintenance easier.

It may appear that water is leaking inside your freezer. Check to see if ice is building up. Sheets of ice forming on the bottom of the freezer may be the result of water overfilling or overshooting the ice tray. Make sure the ice bin is properly installed.

If there's any container left open or not completely sealed, liquid could have leaked out prior to freezing.

Frost buildup may have many causes, and one of them is warm air entering the freezer. Make sure nothing is blocking the door or preventing it from being totally closed.

It could be that the temperature is set too low. If that's the case, try increasing the temperature slightly.

If you add something hot to the freezer, it could cause frost to build up. Always allow food to cool before storing.

Too much food in the freezer will stop air circulation and cause frost formation. Make sure nothing blocks the air vents and try rearranging the food items for better air circulation.
