Touch screen is lighted. No response to touch.

This may be a systemic problem:

:) Luckily, these GE touch screen models can now be affordably repaired.

Full official details on the fix are at http://www.microwavecontrol.com/jvm2070.htm.

Let me know if you have other questions.

If by "touchpad" you mean the touch screen (LCD assembly), those and their connecting strips are very fragile.
If the screen is not lighting after reinstallation, I would first check to be sure the white 3-wire cable is properly plugged back into the lower power board.
If it is, and everything is connected correctly, then you may have received a defective touch screen (LCD assembly) and would need to return it for replacement.
Again, these units are very delicate and the connectors are finicky.
I have an unedited video that shows you how to remove the LCD assembly. It would be useful in reassembly as well.
It is here:

GE has a special program, and your microwave is very likely a part of this program. Please contact GE consumer relations asap at 800-386-1215, at the prompt press 5. Our same microwave model has that problem. GE is replacing the entire microwave free of charge.

The L on the screen was for lock on the unit, the memory may have gotten corrupted due to a voltage spike. Try holding the start button for 4 seconds to unlock the unit.

Hope helps.

Check fuses that are more than one inside the cabinet

Two possibilities...the controller has failed -- buy new microwave!
Second possibility...many microwaves have a child lock feature. Open the door up and read the labels stuck around the door frame of the cooking cabinet. If yours has this "child lock" feature, it will tell you how to unlock it.

If this helps you, please select YES to one of the first two ratings questions. Thank you, and Good Luck.

try opening up the control panel,disconnect the connector ribbon coming from control panel and connected 2 control board by just pulling it out and cleaning end of connector ribbon and iserting it back.some times this works.if not then 4 sure touch panel needs to be replaced.

Replace keypad

This is a problem with the control panel assembly, which we commonly repair for $32.50. Feel free to e-mail me at _ for more information or visit _ for full details.
