I have a new Fridgedair Fridge and new (4 yo) Maytag "Commercial Quality" washer and dryer. I have a warranty on the fridge and have spent almost 1000 dollars on repairs already. The repair guy told me never to buy a fridge without it. The door stopped working! I didn't get the warranty on the washer and dryer but I should have. In the 4 years of owning them I have DIY replaced the gearbox on the washer, 2 heating units, a tensioner pully, and all rollers in the dryer. One of them is starting to squeak again and the belt needs replaced. It's really been nonstop and the gearbox fix, if done by a professional, was more than the thing was worth.
