Crackles even after blades are cleaned
To stop the crackling sound, you need to remove all of the dust particles from the wire in the back. Sometimes when the unit is extremely dirty you can see sparks emanating from the wire, this is what causes the crackling sound. The unit has a built in cleaner you can lift up and down to perform this task, located on the top, but this doesn't work extremely well.
I usually take a can of compressed air and blow as much of the dust I can off the wire and all surrounding internal areas as I can. To do this, approach the unit from the front, and turn the blade door slightly so the wire can be seen. This along with a thorough cleaning of the blades should eliminate the crackling noise. Of course, make sure the device is unplugged before performing any cleaning.
