Maytag had lots of problems with the control on the 701 dryer which is why later top of the line dryers with the electronic dryness control used the "Highlander Controls" with the 4 buttons or the 4 settings on the dial and Maytag stopped trying to combine a timer with the electronic dryness control, according to veteran Maytag Service Techs.
Greg, I hope yours works perfectly. Please let us know if the dial moves on the timed settings.
You can take the top off the KDS55, slip some insulation between the tub and the outer cabinet, do the thick fiberglass behind the lower front panel, sound panels on the inner door and a KA washer sound pad on the bottom of the shell, like they do with the washers and quiet it down a good bit. While you have the top off, slap some epoxy paint on the cabinet around and above the fill air gap so you won't have rusting. My 58 is quieter than the 18, but not by much. Phone conversations are possible when either is performing.
