I am currently working on an older Kitchen Aid electric dryer model number KEYE670BWH2. The dryer was dismantled and cleaned ,reassembled, and hooked up to power. When cold it will start the drum turning and heat well. If the door is opened for any reason after it has warmed up it will buzz and then kick out the overload protector of the motor and will not restart. I have seen this before on other electric dryers and presume the motor bearings are worn and there is too much drag. Is it also a possibility of the blower being the source of the drag ? With the belt off the motor the drum turns fairly smooth by hand. The motor turns OK but not as freely as a new one. Also how do you get blower apart to clean debris out of the inside ? Need advice ASAP.
