Thank you for using Just Answer.
This is a new model. The procedure is to press and hold the "Alarm/Light" pad for 10 seconds (to be sure). It actually says 3 seconds in your manual.

It could be you are not getting 9 volts dc from the main electronic board in back of refr or the board in the dispenser is bad . This refrigerator is loaded with electronic components . This is a fairly new model and should be under warranty so anything you try yourself will void the warranty . Call where you purchased it and get a qualified service tech to check it. If this aswer is satisfactory please hit the ACCEPT button.
From the procedure that you did, you did get something good. The fact that you received that response is a good thing.
Try this -
Unplug the refrigerator for 15 minutes (or a little more) and then plug it back in. This may reset the display.
Did this model just start doing this? How did you find this to happen?
Are you talking about the light that is also the nightlight?
This model has a one year complete warranty (from date of purchase). So, if you can not get it to clear then you absolutely want to have GE service the unit. If the board is bad and/or the dispenser panel is bad it will be expensive in parts alone. GE will do this at no charge during the first year.
Let me know if you need any more information.
