Dimmer Switch energizes BOTH the fan and light, instead of only the light.

Dimmer Switch energizes BOTH the fan and light, instead of only the light.

I installed a Maestro Lutron w/Companion 3 way dimmer switch to turn on/off the ceiling fan. I wired it exactly as the two original 3 way switches. Now, I get a hum on the ceiling fan and when I increase and decrease the dimmer, both, the light and the fan turn on and off, respectively, at the same time.

What do you think it could be?

Let me clarify. My intent was to turn the fan on with the button and use the dimmer to turn on the light. Except both are turned on or off when I increase or decrease the dimmer slide.

I'm not sure where the problem lies.

A fan motor should never be on a dimmer switch. You need one supply for the fan motor and one supply for the light. There should be two switches not one if you use a dimmer. Or if you have pull chains on the fan you can connect the motor only straight to the power supply and only switch the lights.

Tell us the wiring to the fan. Do you have a cable with red, black, and white wires at the fan? Does power come in at the fan or one of the switches?
How did it work before the dimmer.
