Product review (4 stars): Works Fine
Bought for a Kitchen Aid KBFA 25ERSS01.  Although the specific KA part was much more expensive, I cross matched this filter and it works fine.  I originally thought the 10 year old filter was plugged, but the reservoir for the cold water behind the sliding drawers had a frozen spot.  Replaced the filter, still no water.  Took out the drawers and barely hit them with a hair dryer and there was success.  This was after removing the switch nozzle and testing the switch which was good.  The last thing that may have been wrong would have been the solenoid driven switch (I assume this is how water is valved).  Entire repair took about 25 minutes.
