This is excellent material and something that I want all of my Eagan homeowners to know about.  DIY is great, if you know what you're doing.  Thanks Reuben!

I love dimmer switches; I use them to control almost every light in my house.Installing a dimmer switch is a common enough DIY project, but like any other DIY project, I often find them installed improperly.  The most common problem I find is when dimmer switches are connected to a ceiling fan.

Standard dimmer switches should never be used on ceiling fans because they could damage the fan motor or they could overheat and start a fire.  To know whether a dimmer switch is intended for use with a fan, all you usually have to do is remove the switch cover; there is typically fine print right on the front of the switch saying whether or not it can be used with a ceiling fan.

The photo below left comes from a fan speed controller - this is what needs to be used on a ceiling fan.  The photo below right comes from a standard dimmer switch, and this should not be used on a ceiling fan.

When I find a dimmer switch that is designed for incandescent fixtures connected to a ceiling fan, I always recommend repair.  A safe repair can be as simple as replacing the dimmer switch with a standard toggle switch, but you also lose the ability to dim the light.

If the wiring for a ceiling fan is already in place in your home (ie - you have separate wires for the fan control and the light control), it should be fairly easy for a qualified person to wire up separate controls for the fan and the light, which will include the ability to dim the light.

Well, I certainly didn't know this.  And, I have one.  Ooops.  I'll have to check it out.

You, by the way, have a pretty famous name around here!

I do or Reuben does?  I met Reuben once or twice in my office - he really struck me as a tremendous fellow.
