Query: Good while they last but it has a short life span

We purchased our first Haier 1700 at Brandsmart for $137.00 three years ago along with an extended warranty. After one year we turned it in for a replacement because the temp. was unstable. The second one lasted two years before the door broke, and the convection fan stopped. I love the price and the size. It accomodates a 1/2 size baking pan. It's great for about a year or two at most.
