I had that same problem before I put in a dedicated line. The switch for the ceiling fan was one that allowed you to increase or decrease the fan speed. I changed the switch to a simple on/off switch and the hum disappeared.
What power conditioner will help in my situation?
The only power outlets I have are on the same circuit as the ceiling fan. When I change the fan speed there is a low frequency hum when I turn the fan speed from low to medium etc.
Aside from running a dedicated line, will a power regenerator or conditioner eliminate this?
