The light is a current outer orbit light fixture, and the problem is that the built in fans are not turning on any more. Any way to fix my problem.
Did you check them out? Like a computers cooling fan, it can get clogged with dust, debris, etc. that will cause it to slow/stop turning. A good vacuuming or shot of compressed air (away from tank) should clear it. The other possibility, is that's its reach it life span and needs to be replaced.
