I have been told that there are very few appliance manufacturers left:
Whirlpool, Fridgidare, Electrolux (which also owns half the chain saw brands!). Also Bosch and Samsung, and a few smaller companies.
But all the 'brand names' like Amana, Kitchen Aid, Maytag, Kenmore, etc. are made by the big 3.
So, just like your grandfather's McCulloch or Homelite is not what it used to be, forget the lonely Maytag repairman thing as well.
A few years back I bought a Maytag dehumidifier at the Home Depot, partially due to the name. It broke. Maytag said, "Oh, that's not ours." I got a list of 'official' repair sites for the non-Maytag Maytag. I called the closest one, about 20 miles away, across the city. Guy says he works out of his home, but he is not home during the day. 'Just leave it in the driveway, under the basketball hoop with a note on it, and I will get back to you in a few days'. Could I make this up? Took it back to HD and got a refund.
