There are only a limited number a major appliance manufacturers left in the marketplace. Over the years, the big ones have bought up the smaller ones and merged those product designs into their own product lines. They now produce products under the various brand names they own.
Often there is only cosmetic differences in the appearance of the appliance, while the underlying mechanical workings are very similar, if not the same. The manufacturers warranty may also differ between brands and models.
To aid in comparing new appliances, I have compiled a list of some of the major appliance manufacturers and the brand names they own. I have also tried to note where a product with a particular brand name varies greatly from the other brands of the same manufacturer.
