Query: Piece of junk...

I bought this item for my office about a year ago. From day one, the fan made a terrible clicking sound unless the heater was propped up from the back to put the fan in a different rotary plane. Then, as I turned the thing on this Fall....nothing. No fan, no heat, no control panel lights...nothing at all. It's headed for the dump.
