Maytag Stacked W&D
This exact model was sold from 1985- the early 90s after which all MT stacks were mechanical controlled and continued till 2006 when WP closed the factory.
All these MTSs had electronic dryness control, they all were were just one speed washers however. The washer was Mts standard capacity and the dryer was on the small size for a 27" wide machine [ smaller than FDs & WPs 27" offerings ]
Most of the mechanical parts were the same as MTs standard DC washers and SOH dryers, the dryer had a unique motor and a little lower wattage heater element.
Biggest problem with this set-up was getting the dammed thing level, the combined machine has EIGHT feet that all have to be exactly adjusted to the floor surface and then there are EIGHT lock nuts on the feet that have to be tightened to keep the feet in place. Try doing this when the thing is in a closet and you cannot get to the sides or rear of the machine, needless to say only about two of these machines were ever installed properly.
Other than these short comings these were pretty good machines, they tended to have around 3-6 service [ repair ] calls in their average lifetime of around 15-30 years, We still work on several of these machines every week here in the DC area.
