What to Do If Your LG Filter Is Stuck?

What is the safest way to remove the cartridge if it gets stuck? If you experience this issue, here are some tips that can help:

  • Always remove the uppermost shelves from the refrigerator when accessing filters located in the top corners.
  • It is easier to remove other filters when the dispenser’s pressure is reduced. To release the pressure, make sure to dispense any remaining liquid in the dispenser after turning off the valve to release the pressure.
  • If the problem persists, call in a trained technician to help safely replace the cartridge.

If you still can’t get the old filter out, you’re likely going to need to call a service tech. Companies like FilterWay can assist you with this service or don’t forget you can ask your Realtor for recommended local experts. 

The Importance of Regularly Replacing Your LG Filter 

You should change your refrigerator cartridge at regular intervals of six months to one year because the life of the unit depends on how much water it has to purify. The more water that passes through the cartridge, the more dirt, and particles it can trap and remove from your water. If you do not periodically change the unit, it will eventually stop working properly and need to be replaced.

A dirty or old refrigerator cartridge can lead to a host of problems with your refrigerator, including:

  • The water in your refrigerator is not clean enough for you to drink.
  • The water in your ice maker is no longer clean enough to use as a source for making ice cubes.
  • The smell of mold and mildew inside your refrigerator. 
  • There will be reduced efficiency by your appliance which leads to increased energy consumption and expense.

Final Thoughts

Clean, pure water and fresh foods are some of life’s greatest pleasures. LG consumers are lucky to have access to a wide selection of products that provide these essential needs. 

However, regularly checking and replacing the cartridges is vital for the health of your home and family. You only need to follow these simple steps on how to replace the water filter in the LG refrigerator to get it done. Enjoy!
