I have a queen size microplush with dual controls.  This is a replacement for the one that I returned in January which also malfunctioned.  Getting a replacement was 
such a hassle.  And now only one side of this blanket works.  One side flashes F2 constantly.  I unplugged the blanket from the wall and now - 10+ hours later it still flashes F2.  How is this possible?  The last working Sunbeam blanket I owned  lasted 38 years - and now this?  I'm done.  Cutting my losses and will never buy Sunbeam again.
