control panel replacement

[SIZE=4]I recently wrote and inquired about error codes on my Whirlpool double oven. We ordered a touch control panel and my husband installed it. After one use of the oven. The oven started doing the same thing again. No digital readings, oven won’t turn on, and no clock. However you can turn on the light with the control panel.
If you have any suggestions I would GREATLY appreciate it. Here we thought wow we fixed it ourselves and for half the price of the part that the service man wanted and that wasn’t even including labor.:frowning: [/SIZE]
