Call twice about this unit and not one person will call me back and if there is a chat support I can’t get it on my computer.  I am so upset I still have a bar table sitting on my living room floor not put together because of parts that are defective so I guess I will be adding a range hood.  I like the range hood but it won’t turn on and I can’t put it up if it doesn’t work.  Come on people if u can’t help me then I will need to send it back
