Is this unit no longer being made? I have a brand new still in the box that I just came across in the basement. Can I sell something that is no longer being made and will whirlpool still have parts for this? I think I bought this in 2002. Can you tell me what they sold for new? Thank you? white window unit 13" H, 18-1/2"W, 15"D, 5000 BTU cools 150SF if that helps.
