Changing a Refrigerator Water Filter

Replacing your refrigerator water filter regularly is an easy way to improve water quality and extend the life of your appliance. Here is a comprehensive guide on when and how to change a refrigerator water filter.

Why Change the Water Filter?

There are a few key reasons to change your refrigerator water filter on a regular basis:

  • Remove contaminants – Over time, water filters become less effective at removing contaminants like lead, chlorine, and particles. Replacing the filter ensures you get cleaner, better-tasting water.
  • Improve water flow – As filters collect particulates, water flow can slow down. A new filter brings back full water pressure.
  • Extend appliance life – Clogged filters make refrigerators work harder and run less efficiently. Fresh filters keep things running smoothly.
  • Follow manufacturer recommendations – For optimal performance, most brands recommend changing filters every 6 months. Check your owner’s manual for specific guidelines.

How Often Should You Change the Filter?

Most refrigerator manufacturers recommend replacing water filters every 6 months. However, filter replacement frequency depends on factors like:

  • Water quality – If you have hard or contaminated water, you may need to change the filter more often.
  • Usage – Heavy water dispensing drains filters faster. Households that use a lot of water may need more frequent changes.
  • Filter type – Different filters have different lifespans. Look up recommendations for your specific model.
  • Manufacturer recommendations – Consult your owner’s manual for the interval suggested by your appliance brand.

The best way to know when to change your filter is to track filter life on your refrigerator and replace it when the indicator hits zero.

What Kind of Filter Do You Need?

Replacement water filters are specific to the make and model of your refrigerator. When purchasing a new filter:

  • Check your owner’s manual for the right part number
  • Note if it’s a screw-on, push-in, or specialty design
  • Buy directly from the manufacturer or authorized retailer when possible

Buying the properly sized and designed filter ensures good water flow and filtration. Avoid cheap off-brand or “universal” filters that may not fit right or work as well.

How to Change a Refrigerator Water Filter

Once you have the right replacement filter, changing it out is a quick DIY job. Follow these steps:

Turn Off the Water Supply

Locate the water supply line that runs into the back or bottom of your refrigerator and turn off the shutoff valve. This prevents leaks while you work.

Remove the Old Filter

Your fridge may have an eject button, dial, or handle to release the filter. Otherwise, grasp it firmly and twist counterclockwise to detach from the housing.

Clean the Housing

Wipe out any dust, grime, or particles from the now-empty filter housing using a cloth or sponge.

Install the New Filter

Remove the new filter from packaging and align into the filter housing. Push firmly and twist clockwise to lock it into place.

Flush the System

Turn on your water supply and let 2-3 gallons of water run through the filter to clear air pockets and unfiltered water.

Reset the Filter Light

Consult your owner’s manual to reset the filter replacement light or timer back to zero.

And that’s it – you now have a freshly filtered water supply from your refrigerator. Be sure to date your filter replacement on a calendar reminder.

Troubleshooting Common Water Filter Issues

If you encounter any problems after changing your filter, here are tips to get your water flow back to normal:

Clogged or slow dispenser:

  • Flush the system well with 2-3 gallons of water
  • Ensure filter is fully tightened in housing
  • Replace filter with a new one

Leaking connections:

  • Check that connections are firmly hand-tightened
  • Examine o-rings for damage and replace filter if worn
  • Wipe down interfaces to ensure a tight seal

Cloudy or bad tasting water:

  • Flush 2-3 gallons through a new filter to clear residual particles
  • Double check your new filter is the correct model for your refrigerator
  • Replace with a fresh filter

Filter indicator not resetting:

  • Consult your manual for proper reset method
  • For dial or button indicators, press and hold for 10+ seconds to reset
  • Try unplugging fridge power cord briefly to reset

If problems persist after troubleshooting, contact the refrigerator manufacturer for additional support.
