One of the baffles broke off the tumbler and need to replace it

correct no repair guy neede unplug the unit so you dont get electrocuted happen to me once dont let it happen to you. remove the front panel than undo two screws at top of cabinet to release the top rotate the drum so the baffel you are replacing is at the 12 oclock position insert the baffel rub the screws thru the factory holes at top of unit if the holes are stripped dont be afraid to throw a washer in with the screw and dont over tighten because they will stripp out the plastic baffel . reasemble and your done takes about ten minutes
