Try using compressed air under the knob to see if that helps If not you can remove the knob by prying it off with a trim removal tool, and trying cleaning the contacts with some electrical cleaner If that doesn't work, then it could be a electronics problem, in which case the easiest solution is to buy another controller and replace the faulty one Good luck |
