LG Water Filter Cap (ABN73019101)

The LG Water Filter Cap covers and secures the refrigerator’s water filter in its housing. It helps hold the filter in place so water is directed through the filter instead of leaking around it. It also protects the filter area from bumps and debris and lets you remove and reinstall the filter during routine service. Common causes of failure include cracked plastic from impact, stress from repeated filter changes, stripped or worn locking tabs, and damage from overtightening. A cap that does not seat flat can also let the filter shift, which may lead to leaks or poor sealing. These symptoms can help you decide if this cap matches your issue: Water leaking or dripping from the filter area after replacing the filter The cap will not lock, clicks loosely, or pops back out Visible cracks, chips, or a warped cap that will not sit flush The water filter feels loose or will not stay seated in the housing Difficulty removing or reinstalling the cap due to broken or worn tabs
