How to Reset a Maytag Refrigerator
After replacing the water filter on a Maytag refrigerator, you need to reset the refrigerator so that the water filter status light no longer says "REPLACE." Depending on the quality of the water and how much you use the filter, you should replace the filter about once every six months.
Find the "Filter" button on the front panel of the refrigerator.
Press the button.
Hold the button for three seconds. The status light will change from "REPLACE" to "GOOD."
Release the button.
