Master Bob,

I followed your directions as listed below. Unfortunately, after completing installation, I’m not getting any response from the ceiling fan.

I have two questions for you in light of this failure:

1) When I connect two wires together, should I cover them in electrical tape before I put a wire cap over them? I didn’t do this, but have this sneaking suspicion that a wire came loose from one of the wire caps. I taped over the wire caps.

2) Should I experiment with the red wire by connecting it to the black wire from the fan remote controller? The red wire is capped and not connected to anything at the moment.

Also, I have the remote controller dipswitches coordinated with the remote itself.

Thank you so much for your help with this.

Question -

Master Bob,

I’m installing a ceiling fan in a relatively new home (2003). There are two switches on the wall. In the outlet box, there are 4 wires (Red, Black, White, and Bare).

The fan has a remote controller (dimmer) that has two wires that are to connect to the outlet box. They are black (marked AC in L) and white (marked AC in N). Going out of the remote are three wires (black (marked To Motor L), white (marked To Motor N), and blue (marked For Light).

I would like to know if I should connect the Red wire from the outlet box to the Black wire on the remote controller or the Black wire from the outlet box to the black wire on the remote controller. I assume white goes to white and that the bare wire goes to the green wire that comes with the ceiling fan bracket.

Hi Brian,

Based on your decription. this home was wired in the common fashion. with a run of 12/3 from two wall switches — 1 switch to control the fan motor (on black) and 1 switch to turn light kit on and off(on red). This is a typical layout and works great until you throw in a remote contol unit. and now the 12/3 and the 2 switches don’t play much of a role (most remote control fans can be wired with 12/2 and 1 switch. with the remote controlling all functions [lights and fan motor] from the ground — the remote has complete control of fan speed and light intensity).

Perhaps your model has an alternative wiring layout. but here’s whats normally done in that scenario with most fans that have a remote. At the ceiling box — The red of the 12/3 is not used. it is simply capped off with a wirenut.

The black of the ceiling box goes to the black in of the remote control unit. The white of the ceiling box goes to the white in of the remote control unit. The 3 outgoing wires of the remote connect as you have then written. black to the motor line, white to the motor neutral and blue to the lights power wire (typically also blue)

Down at the switches boxes. one won’t be used and a blank cover plate can be installed over it. only the switch that controls the black up to the ceiling box will. This switch will now turn the light/fan on off. with the remote controlling all other functions. Typically. this one switch is always left in the On position. so that the remote receiver is always powered up. waiting a command from the hand held remote transmitter. But that depends on what type of remote you have. and if it also controls motor speed, light intensity and can shut one or the other. or both — off.

Of course. you could always not install the remote unit up at the ceiling box..(and wire it in the normal fashion)..and just let the switches turn the light or fan motor on and off. but I’ve found most people want the remote control feature.

It all depends of what the end user wants. and what type of remote control is included. as to how it will be wired.

Hope this helps. if you need more detail or have new questions, please follow-up.

Best Wishes,

Hi Brian,

Thanks for following-up. sorry just responding — have been out of the area on an emergency call..

Generally, putting tape over the conductor part of the wires before spinning on a wire nut won’t help the connection. if the end of the wires are stripped the correct length and the wire nut tightly installed. this connection should be solid (we usually do a quick » pull test» to make sure the wires are solidly connected together under the wire nut) — Putting tape over the conductor section may actually impede the physical connection made by the wirenut. However. a wrap of tape around the wirenut and wires AFTER the wirenut is screwed on will help insure the wire nut stays tight. and help keep any wires from coming loose or coming out of the connection.
