William S Fleetwood , NC December 23, 2020 Appliance: Kenmore Freezer 25328092803 Kenmore Freezer 25328092803: Random open door alarm. Temperature fluctuations. Light remaining on when door was closed. How to replace Control Display Unit. I replaced the control and it was a super-easy replacement. The only tool needed was a small flat-head screwdriver to pry the existing panel off. The new panel slid into place and Bob's your uncle!
