Is the water or ice in your fridge starting to taste a bit… off? This is a clear indication from your fridge that it’s time to replace the fridge water filter. Don’t sweat it, though! This is one of those jobs you can do right from the comfort of your own home!
As local fridge repair technicians in Charlotte, North Carolina, we’ve helped plenty of homeowners change their fridge’s filter while also teaching them how they can maintain this on their own. Thus, we’ll walk you through how to replace a refrigerator water filter step-by-step, explain the different filter types, and share how to keep your drinking water fresh and clean all year long!
The 3 Different Types of Fridge Water Filters
Before you run to grab a new filter, it helps to know which kind your refrigerator uses. There’s nothing worse than buying a new filter and having to go back to the store because you picked out the wrong one (it happens to the best of us!).
Most fridges have one of three common filter styles: push-in (or twist-in), slide-out (or pull-out), and in-line filters. Each one connects to your water line a little differently.
1. Push-In or Twist-In Filters
These are the most common and are often found inside the fridge – either in the top-right corner or at the bottom front grille. You simply twist or push them into place. The filter has locking tabs that secure it, so no tools are usually needed.
A couple brands that commonly have this type of filter include GE fridges and Whirlpool fridges.
2. Slide-Out or Pull-Out Filters
These look like a small rectangular cartridge. They’re usually behind a cover or latch in the refrigerator compartment. You’ll often find them in newer models that focus on easy maintenance.
Normally, brands with sleek and modern designs use this type of filter on their fridge, like KitchenAid fridges.
3. In-Line Filters
These are located behind the fridge, connected directly to the water supply line. You’ll see a small cylinder attached to the tubing. They’re common in older fridges or custom water setups, and they may require a wrench or pliers to remove.
How To Change Your Refrigerator’s Water Filter
Each filter type has a slightly different replacement process. Let’s go over how to handle each one safely and efficiently!
How To Replace a Push-In or Twist-In Fridge Filter
1. Turn Off the Water Supply (if needed)
Most fridges allow you to swap filters while water is still on, but if you’re unsure, turn off the water valve behind the refrigerator or under your kitchen sink.
The valve will have a small lever handle or a round knob, often made from some type of metal. Most refrigerator manuals will also mention the location of the water valve if you can’t find it on your own, so that can be your last resort if you’re unable to spot the valve!
2. Find the Filter
Open your fridge and look for the filter compartment. It’s usually in the top-right corner or behind a small plastic cover.
3. Remove the Old Filter
Twist it counterclockwise or press the release button (depending on the model) until it pops out. You might hear a small hiss, but don’t worry, that’s normal as the pressure releases.
4. Install the New Filter
Line up the notches and insert the new fridge filter. Twist clockwise or push it in until it clicks. That “click” sound means it’s sealed properly!
5. Flush the Filter
Run water through the dispenser for about 2 to 3 minutes. This clears out any carbon residue from the new filter, so you can enjoy your clean water and ice right away!
How to Replace a Slide-Out or Pull-Out Fridge Filter
1. Open the Filter Cover
Look for a small panel inside the fridge, usually located near the top or behind a door in the upper section of your refrigerator.
2. Remove the Old Filter
Slide it out gently. Some models have a release button; others pull straight out.
3. Insert the New Filter
Align it with the slot and push it until it locks into place.
4. Flush and Reset
Dispense water for a few minutes, then reset the filter indicator light if your fridge has one. Most lights reset by holding down the “Water” or “Filter Reset” button for 3 to 5 seconds.
How to Replace an In-Line Refrigerator Filter
1. Unplug the Fridge and Turn Off the Water Supply
Safety first! Always unplug the fridge before working behind it. This guarantees that you’re free from any potential electrical hazards in Charlotte. If this is uncomfortable for you, it might be best to call us for fridge maintenance, like replacing a water filter.
2. Locate the Filter
You’ll find it along the water line running to the back of the fridge.
3. Remove the Old Filter
Use a wrench to loosen the fittings on each end. Be prepared for a bit of water to drip out, so keep a towel and bucket handy to catch any leaking water.
4. Install the New Filter
Make sure the arrows on the new filter match the direction of water flow. Tighten the fittings snugly, but don’t overtighten. Overtightening might lead to deformity in the water line that can cause leaks, unwanted water flow, or premature failure.
5. Turn On the Water and Test
Plug the fridge back in, open the valve, and check for leaks. Run water for a few minutes to flush the new filter.
When To Replace a Fridge Water Filter
Most manufacturers recommend changing your water filter every 6 months, but that can vary based on your water quality and how much you use your dispenser or ice maker. In certain areas of Charlotte, the local water can have mineral buildup that clogs filters faster, especially if your fridge gets heavy daily use.
Given these circumstances, it may be best to replace your water filter sooner! Here are a few signs it’s time to replace a fridge water filter:
- The water tastes metallic or stale.
- The water flow slows down.
- Ice cubes are cloudy or have an unusual taste.
- The filter indicator light turns red or orange.
When To Call a Professional Instead of Replacing the Fridge Water Filter Yourself
Sometimes, replacing a fridge water filter at home is straightforward but there are situations where it’s better to let a trained technician handle it. If you encounter any of the following, don’t hesitate to call us for professional help:
- Uncertainty about the water line or valve: If you’re not sure which valve controls the water supply or how to safely turn it off, we can prevent leaks or flooding.
- Leaking or damaged fittings: Cracked tubes, broken O-rings, or worn connectors should be inspected to avoid bigger problems.
- Ice maker or water dispenser issues: Sometimes slow water flow or poor ice quality isn’t just the filter. This could mean a larger internal issue that needs professional fixes.
- Older or unusual fridges: Built-in or custom models may have complicated water systems that require specialized knowledge.
Calling us guarantees the filter replacement is done safely and thoroughly, and it’s also a chance to have us check out other components, so your fridge water system stays in top shape.
Tips for Keeping Your Water Clean and Fresh

- Avoid off-brand filters that might not fit snugly or meet fridge filter safety standards in Charlotte.
- Clean the filter housing occasionally with a damp cloth before inserting the new one to remove any residue.
