Frigidaire dryer lights blinking

Could someone please point me in the right direction. My Frigidaire dryer is randomly blinking all the lights on the front panel. The only way to make it stop is to turn off the main breaker. Sometimes pushing the cancel button will work, but only for a little while.:confused: Thanks.

Here is the tech sheet.

Try to get into diagnostics.
