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.

Ge profile microwave oven touchpad not working


The touch pad is more than like the problem. This is common. Try removing the ribbon connector and reinserting it back in the receptacle. If this doesn't fix the problem then replace the touch pad.

Microwave Buttons Don't Work
Touchpad and Control Panel


If the microwave buttons don't work the touchpad and control panel assembly are probably defective.
Touchpad


If the microwave buttons don't work the touchpad might be at fault. Generally speaking, if the dishwasher display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.
User Control and Display Board


If the microwave buttons don't work the user control and display board are most likely defective and will need to be replaced. If some of the buttons work and some don't, it is more likely a touch pad problem and the touch pad will need to be replaced.
Main Control Board


If the microwave buttons don't work the main control board is most likely defective and will need to be replaced. If some of the buttons work the touch pad is likely the problem. If none of the buttons work the problem may be in the main control board.1_24_2013_5_23_47_pm.gif1_24_2013_5_24_54_pm.jpg

I have the SE code on my Samsung microwave. I have replaced the touch pad but the code remains. Any further advice? What is the purpose of the second tail on the pad; not the one that goes into the plug...


Hello & Welcome to FixYa
SE or 5E means shorted keypad and to solve this problem the keypad needs replacement, if it has already been replaced then it is better to replace the ribbon cable connecting the board. Please get back to me if you have any other questions.

Touchpad will not work after boiling water underneath it for 12 minutes without fan humidity cause touch pad to stop working , I have a GE mdv 2040 with green display touch pad


you can change the touchpad to help with this but whenever you have a microwave over a range you are going to have issues with this. you have to make sure you use the vent on high whenever broiling anything to prevent the moisture from getting in the touch pad because all your touchpad consists of is two stickers and some flat wire so moisture can easily getting into it cause it to stop working for a period of time. but changing it is the best thing you can do

Ge microwave HVM1540DN1BB button control pad stopped working


I am not familiar with the Whirlpool microwaves; however, I just had the same problem with an LG over the range microwave. Several of the positions on the touchpad quit responding to touch. In our case, it was the touchpad itself that was the problem.

The touchpad on our microwave was held in place with adhesive. We pulled it off and replaced it with a new touchpad. Everything works now. The only complication is getting to the connector which carries the signals from the touchpad to the microwave controls. We had to remove and dissassemble the door to get to that connector.

The touchpad cost about $26.00.

Touch pad on microwave doesn't work


HI, since this happen before and it suddenly fixed itself, i don't think its major. i recommend checking the ribbons for a tight fit. theses connection ribbons may be lose or partiality separated form the control board, in return, causing this fault. you can accesses the ribbons by removing the backcover of this unit. if the ribbons are in good condition, i recommend replacing the touch pad membrane.
