Wiring a ceiling fan with two white wires

I am replacing an old celing fan in a house we recently purchased. I have installed ceiling fans before but have never seen two white wires coming from the electrical junction box in the ceiling. Do both white wires from the junction box need to be joined with the white wire coming from the ceiling fan? I also have a blue, black, and a ground wire coming from the junction box which I was going to wire directly to the correspoding wire from the ceiling fan. Any help would be appreciated. Thanks.

 

Are those the only wires in the ceiling box? Is this conduit or cable.

 

Was the old ceiling fan controlled by a wall switch? Is so, one of the white wires was probably from the switch loop, and the other white wire is the neutral.

 

The wires from the junction box are from conduit. There is a split switch on the wall to control the fixture. There are two switches; a slider that you can increase/decrease the power and an on/off switch. I hooked the fan up in the following way: black to black, blue to blue, ground to ground, and then combined all white wires together. The slider switch is controlling the fan speed and the on/off switch is controlling the light. I would like for this to be reversed. Do I switch how the black and blue wires are connected or does this go back to hooking all of the white wires up together? Other than that the light/celing fan works.

look in the switch box to see if the blue wire is the wire running to the switch you want to control the fan.. if it is then yes switch the black and the blue...fans use blue for lights and black for the fan in most cases...check your switch box tho........

 

Also you need to check the voltage both of the white wires at the ceiling to ground. If you show voltage post back.
