Check the main blower. Make sure there is no debris stuck in the fan wheel( squirrel cage) or the blower as this can cause the blower to be out of balance and vibrate. Also check the blower wheel for any up and down or sidevto side movement which could indicate a worn motor bearing. Hope this helps.
