I love mine!
It's quiet (my bedroom is just two steps-or less from the kitchen), cold, energy efficient, and has a light in the freezer!
It's been, overall, very satisfactory. As for the thermostat chip and defrost fan, could happen to any fridge.
My bottom freezer Whirlpool is clearly based on an Amana design....I have the one with the DOOR, which I prefer.
You pays your money and you take your chances--with all of them.
