Hello. My mastercool which sits on the roof vibrates on high speed and makes some house windows vibrate too. I might describe it as more of a shake than vibrate. It just started doing this. Recently I heard a noise and when I checked it a fan blade had broken off the fan. Coild It be that one fan blade missing makes the whole fan inbalanced thus making it shake on high speed? What else might I check and how might I isolate the issue? Thanks all.
