On the hampton bay remote control fan and light module, i do not have wiring diagram. from my ceiling box, i have a red, a black, a white, and a bare copper wire. I think it is because the light switch has a 3 way switch, but i do not know what to connect it to. the module only has a black and a white wire for incoming wires. can you help?

Unfortunately, Mark it's really not as simple as it sounds, to connect the wires properly. Because of that third red traveler wire for the 3-way switch. Actually, ceiling fans don't work well, when a 3-way switch is involved, because it was designed only for lighting convenience. When the fan is turned on, the other ceiling lights will start to glow, whether they are ON or not..

You would be much better served if you can locate another line to come off of and wire to that. Of course,y you won't have the convenience of a wall switch to operate it. But, that's what the pull chains on the fan are for.

Hope this helped you and thanks for choosing FixYa.

Something is fishy here. First: Do you have 2 locations w/ switches or not? If you do then we' ll need to run some tests. You'll need a pigtail neon voltage tester. ($3. or $4. @ Home Depot or Lowe's) test the 3 wires in the ceiling box as follows: touch the pigtail tester to the black & white wire. Did you get a glow? Now try it again on the red & white wire. If no glow on either black or red to white then flip one of the 3-way switches (it doesn't matter which) & test the ceiling wires again. If you had a glow to black & white or red & white before turning the switch you should now have no glow. If you had no glow you should now have a glow to one of the 2 wire sets. Cap off the OTHER one (red or black) because you will Not be using it. Now at the ceiling (with the power OFF!) connect White from the fan to the ceiling White w/ a wire nut & Black & Blue from the fan to ceiling Black or Red (whichever wound up having the power from the 3-way switches. If this doesn't work you will need to call in an electrician because wiring these 3-way switches correctly is one of the most complex things electricians do.
Good Luck!
