Needed new water filter...red indication light on.

Turned the icemaker off (lifted the wire up inside the freezer). Used a pliers to turn and take the circular cover off..located on the bottom of the refrigerator grill..it was tight. Pulled out old filter, put new one on..thats it! Simple. We had to reset the red light inside the refrigerator..pushed it, heard a beep, pushed again, got the green light.
