Product review (5 stars): Pretty easy consumer replacement process - save about half the cost of a service call
Had a GE Profile oven for about 10 years and the display went. There are 2 pieces that make up the display with this being the main one and the other being the touch panel. Since the display was dead I decided to replace this one. Removing the cover on my oven was pretty easy - 2 star bit screws on the bottom and 2 nuts on the back and with a little wiggling, you can remove the top panel.

Unplug the oven before you start the process.

Replacing this involves removing the existing cables and 4 phillips head screws. Take a picture of the cables before you remove them from the dead component so you can make sure you put them back correctly. The ribbon cable that connects the front touch panel to this control unit requires lifting the tabs on the end of the ribbon cable holder and pulling the ribbon cable out.

After removing the cables, remove the 4 screws and replace with the new control panel. Screw in the 4 screws, snap on the cables and then insert the ribbon cable. You need to make sure the ribbon cable goes in even & straight. If it doesn't, you will have either a completely or partially non-functioning touchpad. With the cable in, push down the tabs on the both ends of the ribbon cable connector to secure the cable and confirm it's seated properly.

Before replacing the panel onto the oven, plug the oven into the outlet, hold up the display and confirm the time is displayed and flashing. Then press all the buttons on the front of the display and make sure you see a change and hear the button pressed. If you don't, first thing to check is the ribbon cable is properly pushed in and seated.

I replaced the top of the oven by first getting the top part on over the back and then pressing underneath with my hands to push the metal attached to the main oven up and under the cover you are now replacing, which goes across the entire bottom of the part you just removed. There are some youtube videos that might help, Good luck!
