We grab the air can and blow out behind the needle assemble from both sides, up and down... if you are old and blind like me you can't see where the sensor is anyways but its back there! I figure the lint/dust came from somewhere, might as well blow the whole thing out. When that tiny little electric 'eye' is covered, it shuts you down. IF there was a loud 'kathunk' before it stopped in the down position, that is another expensive repair (thank goodness we bought the extended warranty!) =========================================================== The AmayaUsers Mailing List Website: http://www.amayausers.com Discussion Board: http://www.amayausers.com/boards Subscribe/Unsubscribe: http://www.amayausers.com/list ===========================================================
