Thanks, Bruce. I don't recall seeing any evidence of any grease having ever been in or on my units when I dismantled them. Based on the shape of the outside of this aluminum box, I'm sure there is a heat sink purpose to it. When you get it apart, the portion you can see is amazingly simple. I didn't describe it well, but it's obvious when you see it. What is in the sealed portion behind that "contact strip" is anybody's guess, but it does not appear sevicable (except by Art with a hacksaw).
