I have this exact Model 233.5993 Range Hood. It came with our 4 year old home so I did not witness the installation. I liked this Range Hood until the switch stopped working correctly. I ordered a new 'user interface assembly' (on/off/high/low/light switch replacement part) because the on-button for the light quit holding in the on position. The replacement part was relatively inexpensive. I have now discovered, however, that the decorative stainless flue cover is difficult to remove (apparently secured from the inside to wall mounted brackets) and will likely require me to call the $$ professionals to change out a simple replacement part. I see Sears offers a 5 year extended warranty. That is probably a good idea if you decide to purchase this Range Hood.
