Product review (5 stars): It fixed my Maytage Dishawasher Model MDB7759AWB3
This little critter fixed my 5 year old Maytag dishwasher Model MDB7759AWB3...

Here is the backstory:
Saturday morning (5/13/2017) I awoke to find a "Powerless" control panel (Touchpad) on our dishwasher. Therefore I immediately called Maytag customer service and they advised me the unit no longer had factory warranty. They added that it could be one of several major components the failed (not helpful). I then began using the internet to help diagnose the specifics and found on many repair blogs that most service technicians (mis) diagnose this as needing the control panel and/or the circuit board replaced - each component is approximately $150 plus range plus labor which would result a $500 repair cost! We only paid $599 for the dishwasher in 2010...Reluctant to go this route I dug deeper and found a YouTube video describing the exact scenario I was experiencing.  In this video , it was suggested to check the Thermal Fuse for failure as it would cause the entire control panel to become inoperative. I did just that and followed the video which instructed you to remove the door perimeter screws and access the control panel unit. Then test the fuse for resistivity using a Volt-Ohm meter and in my case the fuse failed the test and showed "1" meaning there is NO continuity in the fuse.  Anyway I immediately went to Amazon to find the replacement thermal fuse of which they did carry and it was prime eligible.  It arrived on Monday (5/15/2017) and I completed the repair by installing the new fuse and kit - Make sure to follow the instructions that come with the new fuse (kit)...Hope this helps!
