| Hampton Bay Fan Motor Noise ??? Our Hampton Bay ceiling fan/light combo (mdl AC-552 "MM""YL") makes noice only when the fan is on (loud humming - motor probably.) The noise diminishes greatly when the light is then turned on. The unit is on a wall rheostat power switch to dim the light and control the speed in addition to the 3 step speed of the unit. Please, how to fix? Is the rheostat incompatible with this unit? |
