LG Refrigerator Air Filter Stuck – Quick Fix

Start by removing the shelf at the top so you have easier access to the filter. Next, hold the air filter with the left hand for stability and hit it towards the left with your right hand. This loosens it from its stuck position. But it does not fall because your other hand catches it.

LG Refrigerator Air Filter Reset

To reset the air filter light or sensor after replacing the filter, press the Air Filter button on the panel and hold it for about 3 seconds.

Usually, the air filter light starts blinking when the filter is due for a change. It will keep blinking until you replace the filter and reset it. Even if you reset it without changing the filter, it will start blinking again shortly after.

However, if you have replaced the filter and the light keeps blinking, ensure you used the right type for your LG refrigerator and it is installed correctly. Otherwise, consider testing the control board and replacing it.

If the water filter in your LG refrigerator is hard to remove, try removing the top shelf in the compartment. It may be blocking the way so the water filter cannot drop down far enough to be uninstalled.

LG Refrigerator Water Filter Not Working – How to Fix

If you find that the water filter in your LG refrigerator is not working, consider the following:

Clogging

If the water filter is older than 6 months in use, it is due for a change. Filters remove deposits or sediments in the water supply and over time, the deposits settle and block the flow of water. You may find the filter not working because of the sediments.

Replace the filter and see if there is a change. This is the likeliest reason why the filter is not working.

Wrong Type

Check the type of filter you are using for your LG refrigerator. You must use LG water filters otherwise, the filter won’t work. Make sure to buy using the model number of your refrigerator. Buying from LG is ideal but if you must buy from other sources, be sure to use a trusted OEM dealer.

Improper Installation

Make sure you thread the filter fully into the water filter housing. Tighten the filter properly otherwise, there may be low or no water flow.

You may have to remove the filter and put it back in again; do it right this time. Consult the user manual of your refrigerator for instructions.

Moved Seal

If your water filter housing has a rubber seal, it may have moved out of position when you uninstalled the old water filter.

Check to see if there is a seal where the filter fits in and move it back into position. Do this before you install the new water filter.

Blockage

Be sure nothing is obstructing the tiny holes through which water flows. You may need to clean the housing and holes before replacing the filter. If you are not sure how to do this, hire a professional to fix it.

How Long Does LG Refrigerator Filter Last?

The water filter in an LG refrigerator lasts for 6 months. It must be replaced after this time.

But if you live in a dusty area or in a place that sees a lot of construction, replace the water filter more often.

For the air filter, replace it every 3 months. But just like the water filter, replace it more often if you live in an area where a lot of construction happens.

Will LG Refrigerator Work Without Water Filter?

If your LG refrigerator is a newer model, you may be able to use it without a water filter. To determine this, uninstall the filter in your refrigerator and try dispensing water.

If the dispenser works without the filter, then the refrigerator has a built-in bypass that covers the filter. But if the dispenser does not work, you need a filter.

You may be looking to cut costs on using a filter, especially if the water supply to your house is already clean.

If you already have a filtration system in your home or the quality of water in your area is very clean, you may not need to replace the water filter as regularly as every six months.

However, if you decide to go without a water filter, use a bypass plug. The plug works at plugging the holes through which water flows to the filter so there is no flooding.

LG Refrigerator Water Tastes Bad after Changing Filter – Solved

Replacing the water lines affects the taste of the water. So even if you just changed the water filter, the water may still have a weird taste.

Dispense about two gallons of water to clean the lines. If the bad taste remains, disconnect the unit from power and turn the water supply off. Then, disconnect the water line from the unit.

Now, turn on the water supply and taste the water. If it tastes bad, you know the water from the source is bad-tasting and the water filter is not changing it.

Therefore, check the type of filter you are using. For the LG refrigerator, use only LG brand filters and the right type for your refrigerator model. Otherwise, you may find that the water tastes bad.

Also, make sure the water filter is not expired. Expired filters, even if they are LG brand filters, don’t work at filtering water. As a result, contaminants remain and you also expose yourself to the risks associated with using expired products.

Additionally, impure water from the source tastes bad. The water filter may be working but it can only make it clean, not improve its taste completely.

Therefore, use a system for purifying to solve this problem.

Finally, the water stored in the refrigerator water tank may be stale. If you don’t use the water often, its taste tends to change. And the water filter may not be able to do much to change this.

Run water out of the dispenser and throw out the first two gallons. Taste the water to see if it has improved.

To avoid this, use the water from the refrigerator more often.

LG Refrigerator Reset Button

The LG refrigerator water filter reset button is on the control panel on the door of the unit. It is marked Replace Filter.

The air filter reset button is on the same side as the water filter replace button. It is marked Replace and looks like a small window with dots.

LG Refrigerator Leaking from Water Filter – What to Do

The first thing to do is to determine if the filter is old. One of the pieces of evidence of an old filter is leakage of water. If it has been in use for longer than six months, replace the filter.

Take a look at the O-rings at the filter’s end. They may not be sealed correctly or they may be cracked or stretched.

If any of the above is the case, replace the water filter. Be sure to get one that is the right type for your refrigerator model and that is not damaged in any way.

Next, check the head of the filter for damages. Water leaks easily from a water filter with a damaged head. The only fix here is to get a new filter.

In addition to the above, check the water filter housing. There may be cracks in it, causing water to leak. If you find any, replace the filter housing.

There may be a broken connection between the filter and the refrigerator or the filter is not the right size for the unit. Again, replace it as quickly as possible.

LG Refrigerator Water Dispenser Slow after Filter Change – Solved

Make sure the water valve from the housing supply is open all the way. If there is only a partial opening, the water from the dispenser would be slow.

Ensure you are using the right type of filter. The wrong type slows the flow of water or does not work at all.

Be sure the water inlet valve is also open all the way and is not choked with dirt. If it is, try cleaning the dirt around the mouth. And if this does not work, replace the valve.

Try dispensing about two gallons of water out of the system after installing the new filter. This flushes the system of air. The filter is usually filled with air when it is new and it impedes the water flowing to the dispenser.

Why Does My LG Refrigerator Leak Water?

The following are possible reasons why your LG refrigerator leaks water:

  • Clogged defrost drain
  • Leaking water tank
  • Filled, cracked, or improperly inserted drain pan
  • Leaking water supply line
