There could be a few causes. If using a coil cover, remove it and wash out the black sand. Change the batteries and be sure to check the seal of the door. If it happens when the box gets wet, you may have condenseation in the control box and it will have to be sent back to Fisher. Or a small hole in the wire.

Good luck with the warranty.
