Dishwasher Broken - Which part should I order?

I have a Maytag QuietSeries 300 dishwasher, model MDB9600AWQ.
Several months ago, its display panel started acting funny (only part of the green LED segments actually lit) but it continued working fine - until today.
Today, when I tried to operate it as usual, pressing the Start button, the dishwasher simply wouldn't react. As if the Start button was never pressed.
The Delay button responds. All top buttons (the ones that select the program type) respond. But the Start button seems to be "dead".
I searched http://www.repairclinic.com/SmartSearch/smartsearch.aspx for a logical part (panel or control or something along this) and all I could find was "Board, control": Item # 1173225 and Item # 1074739.
They are both expensive (around $100) so obviously I would like to be certain which part I need to order in order to repair this problem.
Your help regarding which part is defective and needs replacement would be much appreciated.
Thanks, Sam

Sam,
What tests have you done? I note that the service manual is available at your site ( 1055095 ). It could be as cheap as the door switch.

You never absolutely know for sure until you replace something and it fixes it right? Repairclinic.com does allow returns. Just get what you think could be it for one shipping charge and return the unused. You just have to pay for return shipping.
...or call an appliance repair service.

and in http://www.mdappliance.com/WPL-99002795.html it costs only $69.99 but it is listed not only as a Maytag part but also as Whirlpool.
Also, repairclinic.com seems to *not* offer this part.
It can also purchased in partstore.com:

Actually, this part is offered by RepairClinic.com (Item # 1012097, $75.75) but it's not in stock. So there is no point in ordering from them.

Sam,
What makes you think the problem is in that panel? It should be easy enough to short across the switch that you suspect, so if shorting makes the dishwasher start, then replace the panel.. You'll probably need to turn off the water and jumper the door switch to test the start switch so I suggest that you buy the manual. Or call a serviceman. If the service technician broke a part during his repair work you should have pursued that in a timely fashion.

Because the green LED display started acting finicky a few months before the START "button" (if one insists on calling this cheap membrane a button) decided to quit. All other "buttons" on the panel work - except for the START one. The START "button" is by far the most frequently used "button". So it makes sense that it would die first.
On the other hand...

It is still possible that it is only the door switch - if this machine's logic is such that START would refuse to show any sign of being pressed if the door is open.
Either way, isn't the door switch part of the panel? Thus if I replace the panel, I will surely solve the problem. I just hope that the faulty component is not the circuit board... (which costs over $100). At any rate, if the problem turns out to be elsewhere, I can return the item to the vendor, since I always buy from vendors that have a good return policy.
Thanks, Sam

And the answer is... :-) :-) :-)
Sure enough, it was the panel. I paid under $70 (including S&H) for a totally brand new panel and it works beautifully. I am very happy. :-)
Thank you all for helping out with this issue.

See if you can download the service or installation manual. When my Maytag was installed I was looking at the installation manual and noticed by entering some special codes (pushing the buttons in a certain sequence it would do some self testing, etc. If I hadn't been home the manual would have been trashed. Maybe yours has a similar feature.

I did that. The Manual Function Test, which may be started by pressing the NORMAL WASH key 5 times followed by the START key within 6 seconds, cannot be started because... you guessed it - it requires the START key - and the START key is dead. LOL :-)
The Sales Floor Demo Mode, which is started by pressing the EXTRA RINSE keypad 5 times within 6 seconds, works well (except that green LED segments are only partially lit, see previous posts), but it cannot be stopped because... you guessed it - it requires pressing the START key - and the START key is dead. LOL :-)
Thus, my original hunch that it is not the door switch but rather the START key seems to be reinforced by these tests. I can only hope that it is indeed the control PANEL and not the control BOARD.
I will let you know once the part comes in...

Just order another new identical dishwasher. Start replacing parts until it works. Then take back the rest of the new one and get a refund for the parts not used.

LOL, as I posted yesterday, I have already solved the problem, using a much less expensive method than the one you described:
It was the control panel, which can be ordered at PartsTap.com:

Including S&H, it cost me less than $70.
