typically always pull something apart to attempt a fix. I must be getting lazy in my old age, but this post reinvigorated me to take it apart and fix, well at least until a new one comes in the mail. Ebay new $44, normally about $100 to $130. I didn’t have any crazy glue available so just a touch of epoxy should do it. Great fix to verify the diffuser is the problem either for the fix or verify to order replacement. You could always have a burned board if the motor shorted. I should have checked the resistance. Maybe when I get the new one I will repost. I would have like to seen the motor drive it, but it seems to a bit buffered or something. Maybe I will set a time lapse and close the door.
