ceiling fan problem
 
There is a hum comming from the fan and I thought that the dimmer was the reason. I was wrong. The fan is making a low "humming" sound when turned on high. The lower the setting the softer the sound (of course). When I turn on the lights the sound is softer then when the lights are off.

What would be the cause of this sound?

Also, there is about 3-4 ft of excess wire under the cover at the top of the fan. Would the excess wire have anything to do with the sound?

Hello Irishman :)

A couple of quick questions... has the fan always hummed or is this something that has recently started? Have you taken the dimmer out of the circuit completely and put a regular wall switch in its place?

The extra wire shouldn't have anything to do with the hum at all.

PS: Sorry that you weren't able to get your new dimmer working from your other posting.

Fan was just installed last Friday and it has always hummed. The dimmer was the only switch that I have used.

The only real way of knowing if the dimmer is imposing this problem on the fan is to put a regular switch in its place. If the hum continues here's my take. There are some really good fans and there's some really bad fans. The bad fans are... well, here's what Wiki says about them.

From Wikipedia:
Quote:

Many fans, including nearly all those produced in modern years, use a direct-drive motor (also known as a "spinner" motor). While a scant few direct-drive motors are of moderately high quality (notably those used in industrial fans), the overwhelmingly vast majority are cheaply made and prone to noise generation and/or failure. This type of motor is used in all Hampton Bay and Harbor Breeze fans.
Do you own either one of those makes?

Dimmers are not motor-rated . You cannot use one on a ceiling fan. You CAN use one on the light kit, but only if it is wired seperately from the fan motor.

A fan controller may LOOK like a dimmer, but it is designed for motor current.

I no longer think it's the dimmer and I'm trying to figure out what is the problem. The fan is a Hunter fan so I know it is a quality fan. I'm just hoping that it's not something that I need to bring back. any suggestions?

Hunter is known for how quiet it runs. However, fans (or any other motor) aren't SILENT either. How loud is this hum?

Not very loud just enough to annoy my wife.

That extra 3/4 feet of wire should not be there.

All that excess wire can be a problem if it's coiled up over, or worse yet under, that fan cover. It may not cause the hum, but it may cause some other less desirable event.

Trust me on this one....:yes:
