If your Hunter controller looks like the above, then the outdoor weatherproof cabinet has been left open and the sun, rain and/or elements have all contributed to its downfall.

Hunter purposefully do not UV treat this internal part of the controller. Thus enabling them to rule out faulty workmanship on their part if one of these controllers are returned to them. The outdoor cabinet is fully weatherproof when shut correctly. If this cabinet stays shut always, then the panel inside will stay grey just like the cabinet colour. You need to listen and feel for the positive latching sound when closing the cabinet door. Another idea is to use the key to lock the cabinet as a secondary precaution. The NT weather cooks these controllers when the cabinet door is open and there is no warranty for this so please make sure the cabinet door clicks shut.

Hope this helps
