MT TL Stack
came out in 1985, they were were all electronically controlled four around 4 years then they brought out a slightly cheaper model with electro-mechcanical controls, after another few years they dropped the electronically controlled version.
These stack MTs went away right after WP bought out MT.
Stack Mts were and are good money makers for us repair guys, they used most of the same parts as Mts regular W&D, so they had many of the same problems. Loose blowers and bad rollers & idler pulleys in the dryers, bad center seals, water injector, WL switches and main drive belts on the washers.
Overall these MT stacks were just average in durability and had lots of problems with vibration due to the fact the machine has EIGHT FEET and EIGHT LOCK-NUTS on the feet that all need to be adjusted properly for the machine to be reasonably stable. { it almost never happens }
After WP bought MT they put the Maytag name on the much more reliable and larger capacity Whirlpool 27" Super Thin-Twin.
