How to Verify If the ADQ73613403 Fits Your LG Refrigerator
LG water filters often look similar—but each is designed for a specific refrigerator series. Verifying compatibility before purchasing ensures proper filtration and leak-free performance.
Here’s how to find your LG refrigerator’s model number:
1. Inside the Refrigerator Compartment
Open the fresh-food section and look for a label on the side wall, typically near the crisper drawers.
2. Inside the Freezer Door Frame
Some models place the model/serial label on the inner wall of the freezer.
3. User Manual or Packaging
Your fridge’s original paperwork also lists the complete model number.
Common examples of compatible models include (but are not limited to): LFXS30766S, LMXS30746S, LFX31945ST, and other LG French door and side-by-side units using the LT800P-style filter.
Once you have your model number, simply match it with the ADQ73613403 filter listing to confirm the correct fit.
How to Install the LG ADQ73613403 Water Filter
Replacing your filter takes less than a minute and requires no tools.
Follow these quick steps:
- Locate the Filter Housing—Usually found in the upper-right corner of the refrigerator compartment.
- Open the Filter Cover—Gently pull down or press the release tab (varies by model).
- Remove the Old Filter—Twist counterclockwise until it releases, then pull straight out.
- Install the New Filter—Align the notches, insert, and twist clockwise until it locks in place.
- Flush the System—Dispense about 2–3 gallons of water to remove air and any carbon residue.
Your refrigerator should now automatically reset the filter indicator, or you can manually reset it using the control panel.
