Product review (1 stars): The worlds most incompetent service department.
I have the NX584 model but have similar complaints -- it has a meat probe that gives insane temperatures and is unusable.  Samsung is now on its 3rd service call.  The truly sad thing is their own tech service says the part they are giving the serviceman will not work (the problem is a resistance on the main board) but they have to take a half day of our time and try again.  Buy from almost anybody before these incompetents..  Next step is to see if Best Buy will take i back since the service calls started way before the 30 day return period -- but have been dragged into their second month.
