Only can start drum by holding down on/off switch while spinning timer to find only certain sectors of the timer which cause the drum to kick in, often in fits and starts. Once started, often buzzer sounds as soon as you let go of the on/off switch and timer switch. But if you really fiddle with it, you can get the dryer to run and heat normally, sometimes to completion of the cycle. But other times dryer will run and heat normally for 2 minutes then shut down and buzz. Also sometimes buzzer 'chirps' while operating. Lots of strange behavior here. Help appreciated.
