As opposed to what its description says, THIS IS NOT a replacement for the Maytag UKF 7003 water filter...  It lags 2 triangular protrusions under the twist on retainers that hold it snug and allow it to make contact enough that the water dispenser knows that the filter is there.  My guess is that since Maytag is no longer making these filters, their replacement manufacturers have "taken the liberty" of leaving off a CRITICAL part of the product that dooms it to failure when installed in a genuine Maytag refrigerator.
