I suppose it could be replaced, but when a motor made a noise on my original, I discovered it was not made to be disassembled. It had glue and hidden wedges that could not be released without destruction of the case. Rather than tell my wife that I ignored the warranty, and I wanted to "fix" it myself....I wound up getting an identical unit and kept my mouth shut (unless she reads this)..... Send it in if you have to! I'm pretty handy, mechanically.
