Why can’t the refrigerator water filter 4396701 be turned to lock in place?
@lorene56 , Sharon, Compare new and old filter for correct size. Make sure you remove the dust cap/plug from the inlet on new filter. Check to see if all rubber O rings are still attached to old filter and not stuck inside the fridge filter housing. Use a flashlight to look in the fridges filter housing to see if some foreign object is in the way of new filter locking in. Try a little vegetable oil on the new filter cartridges rubber O rings to help it slide easier and lock in. Last of all sometimes it just takes a little more force/strength, let some else give it a try and do not be afraid to give it a wiggle side to side and up and down while pushing in. Good luck.
