I always suspect line noise first, since the controllers seem to last
forever.  Try moving the controller to another outlet (preferably on the
same circuit as the devices to be controlled).  Remove any compact
fluorescent/LED bulbs you may have installed recently.  IE make darn
sure, in an optimal signal setting, the controller is indeed bad.
