My Maytag MDBH949AWB1 dishwasher quit working on me. The control selection lights would work, but the start button wouldn't. I opened the panel up and tested the switches for continuity. All were good, and it was getting power.
I researched the problem online. I found that someone else had the exact same problem. One of the Pros answered the question saying to replace the control board.
I ordered the part Sunday night, choose standard shipping, and it was at my door on Tuesday. It took me 5 minutes to replace and my dishwasher was up and running. I saved $300 (to buy a new dishwasher), which was much needed. Plus the part was $30 less than anywhere else.
