Gary, Congrats on the Maytag pair. My everyday dryer is an electric model that has one knob in the center and has the gold colored portion on the back panel. I have never had a repair on this machine. The dryer is in the basement and no rust anywhere and I bought it new in 1980. My machine has a buzzer in it. Mine is harvest gold. When Maytag was changing the look of their machines, the dealer told me that 1980 was the last year for the center dial machines. He took off $30.00 if I would buy a harvest gold model. I wish I would have purchased the white model instead. It is a very quiet dryer and drys well too. Have fun with the new machines. Gary
