Gannu said:Is it properly mounted? If you have it mounted on brackets, ensure that there are neoprene standoffs between the unit and the bracket. This helps reduce the vibrations to a larger extent.
If it is simply mounted on top of a flat surface, keep some isoprene padding between the unit and the surface.
