Product review (5 stars): YES, YOU CAN DO IT!!
Possibly more money than sense to replace this panel, but we really like the measured fill feature on our Whirlpool fridge and we weren't ready to replace the whole fridge $$$$.  Also, when the unit failed it started randomly beeping, as if buttons were being pressed, and that was SUPER annoying.  (The kids called it the haunted fridge for a while.)

It looks a little intimidating, but it couldn't be easier to swap out this panel.  See my attached photo of the panel slightly detached prior to replacement.  The replacement panel I got didn't have a landing spot for the green ground wire, but it works fine without it connected.

FIRST, turn off the breaker for your fridge.  Open the door and confirm NO LIGHT comes on (i.e. power is OFF).

Pull off the bottom slide tray, then remove two screws.  Lift up from the bottom and swing the bottom away from the door.  Then let the panel down a little until two tabs disengage.  Remove the wire plug connectors and sit the old panel aside.  Take a quick minute to clean the now exposed plastic surfaces (yuck!)  Assembly is simply the whole process in reverse.  Reconnect the wires to the new panel, engage the top tabs, swivel the bottom towards the door, replace the two screws, replace the slide tray.  Lastly, turn the breaker back on.

Reply to me with any questions and I'll do my best to answer,  I'm not a repairman, but I am an engineer.
