I can't get the front cap off the base grill on my freezer/refrigerator to replace the ice and water filter.

Removing and replacing a water filter - base grill location

Filters situated in the base grill (below the freezer compartment) of Whirlpool-built side-by-side refrigerators are relatively simple to replace. Follow these two steps:

1. Grasp the filter's end and make a one-quarter turn to the left.
2. Pull the filter straight out.

To replace with a new filter, repeat these two steps in the opposite order, making sure to first remove the red cap from the filter. Proceed by pushing the filter straight into the slot, and then giving it a one quarter turn to the right.
Note: Replacing this type of filter is quick - there is no need to unplug your refrigerator when replacing it. Also, this filter should be replaced every six months.

Do you have a manual for the refrigerator to check he same

Your refrigerator definitely has a water filter. If you have gone 5 years without replacing the filter, you and your family have probably been drinking contaminated water, for some time. Water filters should be replaced every three to six months. On some refrigerators, and in cases of higher water consumption, the filter must be changed every 60 days. Sears sells replacement filter cartridges for Kenmore refrigerators.

The water filter on your refrigerator is located at the front base of the unit, in the grille, below the freezer door. There, you will see a round cap. Turn the cap counter-clockwise, until the handle is vertical.Then, pull it out of the grille. The filter cartridge is attached to the cap. After removing the cap and filter, slide the cap off from the existing filter cartridge. Slide the cap on to a new cartridge, and re-insert with the cap handle in a vertical position. Push it in, firmly. Then, turn the cap clockwise, until the cap handle is horizontal.
