Unlike many appliance manufacturers that place the water filter in the same location for all models, Whirlpool uses two locations for the water filter on side-by-side refrigerators. One location is similar to the position used on many refrigerators, and the other possible location is slightly hidden.
One possible location for the water filter in a Whirlpool side-by-side refrigerator is inside the refrigerator section. The filter will be in the upper, right rear corner of the refrigerator. The filter is round and twists into its position at the top of the refrigerator. This location is commonly used by several refrigerator manufacturers.
An alternative location for the filter in a Whirlpool refrigerator is in the grill at the bottom of the refrigerator. The grill runs along the front of the refrigerator below both doors of a side-by-side model. The in-the-grill filter location is below the freezer door. The filter is behind the knob in the grill. A quarter-turn twist and pulling straight out from the grill removes the filter. The knob slides sideways off the filter.
Whirlpool Filter Features
The water filters for a Whirlpool refrigerator in either location fit in without a filter housing. For the in the refrigerator, the filter acts as its own housing when it is in position. The grill location requires the knob be attached to the filter to hold the filter in position. For either filter location, the refrigerator water and ice system will function with no filter installed. The grill position requires that the knob be installed even if there is no filter.
When to Replace the Filter
If the refrigerator has a filter warning light, the light will be green while the filter is in good condition. The filter light turns yellow when the filter has approximately 10 percent of its useful life remaining. A red filter light means it is time to change the filter. The filter light is reset by rapidly pressing the filter light switch five times. If your Whirlpool does not have a filter light, the owner's manual states to change the filter every six months or any time the flow of water from the dispenser is significantly reduced.
