Good Afternoon Terry, thank you for your post!

Often constant beeping is an indication that the unit is experiencing a possible error. I under you have tried resetting the dryer by flipping the breaker. It is important to wait roughly ten minutes before turning on the unit. If the beeping continues, then the appliance could be experiencing a communication issue with the control board or a potential wiring failure. I would recommend connecting with a qualified appliance repairman to proceed further.
