Product review (4 stars): solved problem with unresponsive buttons
Buttons on my Jenn-Air Dishwasher became unresponsive so all I could do is start it.  None of the options were accessible other than the 2 hour delay.  I wondered if I needed to replace this button panel, or the circuit board it attaches to.  I ordered this based on some internet research and the reviews indicating a solution to similar symptoms.

The item arrived and I quickly slipped the ribbon cable into the connector on the circuit board without removing the old panel.  This test proved it would resolve the problem.  I proceeded to replace the control panel in position.  The only tools needed are a T-20 Torx driver, and a 1/4 hex-head capscrew driver (or 1/4 inch socket).  Be sure to unplug the dishwasher since removing the circuit board cover exposes some 120V connectors that are not hard to short with a tool or your hand, hence the warning sticker on the cover.

I really have no complaints.  The first panel lasted 10 years, which is somewhat fair considering how things are made relatively disposable these days.  I didn't give it five stars only because I can't get too excited about a replacement part that doesn't upgrade anything.
