Kingston versus Mallory timers, etc.
Maytag, like many other companies used various suppliers for the parts they had to buy, inlet valves Motors timers were the major parts that they got from different manufacturers. They also bought water level switches, and the pushbutton switches for speed and temperature came from different manufacturers at different times.
This was partly so they could be competitive and get the best prices. It was also in case there was a strike at one of the vendors they could keep for their production going.
Overall, the Kingston timer had a smoother better feel but was inferior in reliability to a Mallory Timer. I also saw a lot of contact failures on Kingston timers on Maytags.
In fact, the biggest reliability problem on Maytag‘s from the 70s on were the crappy, Robertshaw, inlet valves, Westinghouse, main motors, and Kingston timers, basically the parts they did not make themselves.
And because Maytag was a much smaller company, they didn’t have the buying clought that whirlpool had whirlpool never used Robertshaw timers in their dryers or Kingston timers in their washers for example, or Westinghouse motors in either washers and dryers, they knew better.
