  2. Take out the top shelf to make space. GF-Take-out-the-top-shelf

How Do You Reset LG Refrigerators After Changing the Filter?

As the indicator light must have turned on to indicate the need for filter replacement, you don’t have to keep it on after changing with a new filter. So, follow these steps to reset the filter system: 

  1. After the replacement is complete, hold the light button on your refrigerator's front interface for 3-5 seconds. 
  2. The light will disappear. Your LG refrigerator is reset. 

This indicator light will turn on again after 6 months or so. 

How Do You Remove a Stuck Refrigerator Water Filter?

Make sure you have enough space around you while making the change. After all, you wouldn’t want to break any part due to forceful pulling. There is always the right method: 

  • Take out the top shelf from the refrigerator's interior if your water filter housing is located at the top corner. It provides more space to pull the filter downward and remove it easily.
  • A backlog of water pressure in the water line can make it difficult to remove the filter. So, turn the water line off, and dispense any remaining water to decrease the pressure before removing the old filter.
  • If your filter’s still stuck, hire a professional service to help you change the water filter.

How Much Water to Flush Through the New Refrigerator Filter?

It is advised to always rinse or flush a new filter with water to open the pores and drain the dust or impurities left over from manufacturing. You can run at least 2-4 gallons of water through the new filter after or before the attachment. It also helps prevent your water dispenser from sputtering due to trapped air in the new filter. 

What Type of Water Filter Is Suitable for My Lg Refrigerator?

Picking out the right option from hundreds of filter styles and sizes might feel like an impossible task. Don’t worry as all the information you need is right in front of your eyes on the refrigerator itself. You don’t need the user manual as the product details are also mentioned on the label sticker or rating plate located on the fridge. 

Every branded electronic device has a model number. So, check your refrigerator model to find the water filter that fits your unit. For example, in LG refrigerators, this label is on a panel behind the salad drawer or an internal wall inside the fridge. The different LG filter models are LT500P, LT700P, LT800P, and LT1000P. 

How to Purchase a Water Filter Which Is Suitable for My LG Refrigerator?

You will find a variety of replacement filters in the market. Besides OEM filters from the LG manufacturers, you will find many compatible aftermarket filters. As the latter is economical, you should know the parameters to check before investing. This buying guide is here to help you choose the best partner for your home and refrigerator: 

NSF Certificated or Not

The NSF is an organization that tests and certifies water filtration products to ensure they meet strict quality and performance standards. We cannot emphasize enough just how important it is to check the standard certification of a product. If you want peace of mind that you have made a good purchase, read the label of the filter to see if it's NSF certified. 


For example, glacier Fresh is an aftermarket manufacturer with NSF 42, 53, and 372 certifications along with IAMPO ,which is almost the same as OEM water filters. These certifications are issued after rigorous testing by government officials to check reliability. So, you know you can trust them.


Installation of the Refrigerator Filter

The installation process for fridge water filters should be designed to be user-friendly and straightforward enough that buyers can install the filter themselves without the need for professional help.

Compatibility of the Filter

Different filters are meant for different refrigerator brands, so double-check the number and name of the filter required for your fridge model. You can search for your required model on the Glacier Fresh website. With the right filter, you can enjoy clean water without worrying about contaminants.

The Cost

After all the research, it all comes down to the cost. Your total cost, including the initial purchasing cost + maintenance charges. As every filter retires after a certain period, it needs to be replaced with a new one. 


You cannot avoid it because clean water is a necessity. An old worn out, or blocked filter can harm your health and refrigerator. So, it's wise to change the filter timely (usually 6 months). You can reduce your expenditure by going for aftermarket filters like Glacier Fresh without compromising the quality. 

Can I Only Buy Them From the Manufacturer?

No, as mentioned earlier, both OEM and aftermarket filters are available in the market. People tend to trust the OEM filters more and pay whatever amount they ask, but you should know better. Trusted and certified aftermarket filter manufacturers like Glacier Fresh can supply you with competitive quality filters with the same compatibility at a much lower cost. The decision is up to you.
