I had to buy this second hood because the first hoods fan never worked. Unfortunately, I had a tenant that never cooked so we did not find out until 8 months in when he left abruptly. We called for a repair. The repair man came out and was going to arrange to put a new part in but never called the new tenant. Again, did not find out until she moved. So complete failure of a unit. I had to buy another one to match other units. Low expectations!
