Product review (5 stars): New & improved design
I just received this replacement part for my KitchenAid trash compactor (Model KUCC151LPA0).  This kit includes a redesigned switch which seems a bit more robust than the previous design.  Now, a new foot button is used to start the compactor, whereas before, I used to lift up on the foot pedal to start the motor.  I'm hoping that this newly designed switch will last longer than the original, which broke after 3 years of very light use.

The installation instructions were straightforward and complete.  To install this new kit, you pull out the compactor, unplug the unit, remove the container (i.e., the drawer), remove the front frame panel (10 screws), disconnect (2) wires to the white push button on/off switch, replace the switch, drill two new holes in the front frame panel (drilling template provided), reconnect (2) wires to the new white push button, attach a new foot button using two supplied screws and replace the front frame panel.  Finally, you need to remove the foot pedal (2 screws) in order to replace the rubber sweep that sits behind the foot pedal (2 more screws).  A new rubber sweep is required because it has a notch cut out for the new foot button that starts the compactor.  Total installation time was about 30 minutes.

No special expertise required to preform this work.  You merely need a screw driver and a small drill.
