dryer turns self on, beeps with lights

For the last 2 years my drier has turn itself on (errie), by green light lighting up and beeping. Sometimes it will stay inactive for a few hours, as time goes by, the spans of the activity shortens to only a few min. in between. I have unplugged it and replugged it and reprogrammed(I guess) again, by resetting cycle. The machine will dry for a few hours without problems- then it will act up again. I unplug the dryer to avoid the annoyance. I even called the Frigidaire hotline and was told that they were not familiar with the problem. Please, what is going on? Model no.

See the attachment for the tech sheet.

The only thing that I believe could do this is the control board.
