Only some of the keys on the keypad of my oven work. I have replaced the control board (computer board), but they keys still don't work. What specific part do I need to replace?

Hello, Thank You for using FixYa. I will be helping you today.You didnt have to change the computer you need to replace the control panel. The control panel is the whole front piece which has the touch membrane on it. This is common on these units.
Thank You and please rate my answer if it was helpful..

I have a very similar oven from Maytag. Had it for 1.5 years before it started to break down. The initial problem was we lost the function of a couple of buttons on the control panel. The cost to replace the control panel was about $400.00 with about $250 for the part and the rest for labor. The buttons weren't all too important (self cleaning, clock, warm) so we kept using the oven instead of paying to have the part replaced.

Our repair guy is cool and tells me the problem with the control panel is that Maytag didn't insulate the computer boards so when you kick up the heat in the oven by using the broil or self cleaning feature, you melt some of the contacts or components. He says we can check appliance repair chat rooms for more information. Sure enough, I found this problem occurs a lot for Maytag. Man they must be making a killing off these parts. I agreed to have my control panel replaced, but told my repair guy if it goes out again, be prepared to install a non-Maytag oven. He gave me all the dimensions of our oven cavity so I can pre-shop for a new oven.

Once I replaced the entire front panel, the numbers worked. I ordered the parts and did the install myself. It was easy. I spoke to a friend who has the same model and her's did the same thing after about 18 months of use. This is a problem with Maytag and I'll never buy another maytag product again. My fridge is a maytag also and the control panel went out on it after 4 years. Not good!
