You open the fridge to replace the water filter and realize you have no idea which one to buy. The model number is the key that unlocks everything, yet most people have trouble finding it. A few quick checks can save you from buying the wrong cartridge and dealing with leaks or poor flow later.
Where the Model Number Hides
Refrigerator model numbers are usually printed on a sticker inside the fridge. Check these common spots first:
- Along the upper wall or ceiling near the front
- On the left or right side wall inside the fresh food section
- Behind the crisper drawers (pull them out)
- On the edge of the door when opened
- Near the bottom kickplate on some models
The sticker often shows both the full refrigerator model and sometimes the filter part number directly.
Manual vs Physical Inspection
The owner’s manual is the fastest route if you still have it. Flip to the specifications or maintenance section , the filter model is usually listed there. If the manual is missing, physical inspection inside the fridge works just as well. Many newer models also display the information on a digital screen when you press the filter status button.
Brand-Specific Hints That Save Time
Different brands hide the information in slightly different places:
- LG and Samsung often place the sticker on the upper left interior wall or behind the left door.
- Frigidaire and Kenmore frequently list it near the top or on the door frame.
- Whirlpool, Maytag, and KitchenAid commonly show it on the ceiling or left wall.
- Sub-Zero built-in models usually have a detailed label on the inside right wall or in the control panel area.
If you still cannot find it, take a clear photo of the inside of your fridge and search online using the brand plus “filter location.”
How Do I Find Out What Water Filter My Fridge Needs?
Once you have the refrigerator model number, enter it into the manufacturer’s website or a compatibility tool. The correct filter part number appears immediately. This step prevents buying a cartridge that looks similar but does not fit or work properly.
