I have gone thru about 3-4 fan/light combos. The light portion never quits but the fans stop working pretty quick. Went thru 2 under warranty and purchased one from Amazon. The one purchased from Amazon was same brand the cam with the Clipper. Anyone know of any fixes or more robost brand? I have taken them apart and not seen any weak solder joints or burned components. I have 3 fans of which one works.
