GE DSXH47 turns off w/lights flashing and beeping

Hello - my DSXH47GG0WW unit will randomly turn off, with lights flashing and beeping. If it is left alone, will randomly beep and lights will begin to flash periodically (every 30 seconds or so).

The manual is of no help - how do I determine the error code, and look up what it could be? Troubleshooting section of manual is of no help…Thanks!

did you find out and/or resolve this problem? I am having the similar problem, where my dryer will just start beeping in the middle of the night when not in use.
