Ooops, I wrote resistor. It is a diode and I forgot to warn you about the direction of diode. If you by any chance remove the diode from the casing you need to pay attention to the silver line. In other words, you have to be careful not to turn it around.
Not a problem if you purchase from dealer, because it comes with casing. However, I've replaced these in the past with diodes from Radio Shack.
