We have a 9-10 year old Maytag dryer that has run great to this point. Last night the buzzer wouldn’t shut off (on any of the 3 off settings) and the dryer would not turn off. When the door is open and you touch the switch that the door contacts it will automatically start the dryer. The timer appears to be working, but when time is up the buzzer continues with the dryer. Thanks in advance!
