vibrating stove hood
 

Just got back from three days of sweltering humidity and rain where I used the AC quite a bit in an electric site. Anyway- we started to notice that when the AC was on the fan/hood over the range was vibrating and noisy. I could imake it stop by pushing it up towards the mounting but could not locate obvious mounting screws in overhead cabinet that I might tighten. Anyone ever replace one and have some insight has to how they mount them or how to get to the mounting screws?

Did you lock the outside exhaust damper closed, it will vibrate with the a/c on? The screws for the exhaust hood mounting are on the inside of the fan housing or light housing
