To guarantee top-quality ice and water, Maytag recommends that you change the filter in your refrigerator every six months, and most Maytag refrigerators have a warning light to remind you to do this. The filter is usually on the ceiling of the refrigerator compartment, on the right side, but sometimes, it's in the middle. The procedure for replacing it varies from model to model, but not by much.
If your refrigerator is brand new, you'll find a blue bypass cap installed in the filter receptacle. Pull out this cap and save it -- you never know when you'll need to use the water system without a filter.
Locate the filter
On Maytag freezer-on-top or freezer-on-bottom models, the water filter is located on the ceiling of the refrigerator compartment, on the right side. If you have a side-by-side model, the filter may be located in the center of the ceiling.
Open the filter compartment.
On most models, the bottom of the compartment is hinged and swings down, away from the filter. On some models, the compartment has a hinged cover on the end that swings up toward the ceiling. When you lift it, the end of the filter pops out.
Remove the old filter.
Give the filter a quarter turn to the left -- counterclockwise -- and pull it out. A valve automatically closes behind it to prevent water from spilling out. Empty the water out of the filter and dispose of it. Clean any spilled water in the refrigerator.
Install the new filter.
Remove the new filter from its packaging and pull off the sealing label from the end. Insert that end into the filter receptacle and rotate it clockwise until it locks in place. Close the cover.
Purge the air.
Run water from the water dispenser for about two minutes, or until you get a steady stream with no air spurts. It may take a minute for the water to start flowing, because the filter has to fill first.
Reset the "change filter" light.
Hold down the "lock" button on the control panel on the front of the refrigerator for three seconds while simultaneously depressing the "water" button. On some models, you have to depress the "light" button and "lock" button. If you aren't sure, try both combinations; the correct one will make the light go out.
